It's Christmas Eve in Los Angeles, and Malloy and Reed track down a suspect who beat and mugged a rescue mission Santa, who later gets arrested himself. They also respond to an alcohol-related traffic accident that resulted in a fatality, help a penniless widow who has been detained for shoplifting and take part in the search for a young Native American child who wandered off into a mountainous area while her parents were asleep.

Malloy and Reed drive up on a convenience store robbery in progress, which results in the suspects taking hostages. Later, they pull over a reckless driver who has just committed a heinous crime, learn about a new computer system designed to help them be more productive and finally thwart a group of serial burglars who use motorcycles.

Reed and Malloy have a gun pulled on them after stopping a car that turns out to be stolen, but the contents of the trunk link the two suspects to an even more sinister crime. Afterward, a recently widowed father and his teenage daughter report that their home has just been toilet papered, which ends up being a prelude for a much more serious incident.

Officer Reed, who is an optimist and still has faith in the human race, is subjected to ridicule from Officer Wells after he is swindled twice. On patrol, he and Malloy come to the aid of a woman whose baby has been kidnapped by a heavily armed man seeking a large ransom. Afterward, wells once again questions Reed's judgment during the search for an intoxicated sniper at large.

Malloy and Reed are on patrol, and find a homeless man stabbed. They take a retired policeman, Jack Donohoe (who lives nearby), in for questioning, but he is released when the real suspect is found. Donohoe later gets involved in a shootout with a robbery suspect. Other incidents include an aspiring actress from Missouri shooting up a phone booth at Union Station after being lured by a theatrical agent who promised a movie career and took her money, and then having her suitcase, containing a rattlesnake, stolen at the station.

The officers respond to a shooting involving police and two black men, one of which was shot by one of the officers and later found dead in an alley. The dead man was the younger brother of Reed's friend Kenneth James; his older brother Cleotis was an accomplice and both were members of a black militant gang, The Brotherhood. Kenneth believes the gang's contention that Cleotis was murdered by the officers until the James brothers confront each other and Kenneth learns the truth; his brother Cleotis is arrested after briefly taking his brother hostage. Malloy and Reed also pull over an elderly driver on his 75th birthday for multiple traffic violations.

Malloy and Reed's day begins with a police garage employee taking a joyride in a police car (Code 3), later finding a young woman trying to cash an old age benefits check she found, checking a garage whose closed circuit TV security system was stolen, an elderly woman thinking she saw a prowler, finding a B&E suspect inside a coffin in a mortuary, and poaching into Officer Wells' territory to check on break-ins occurring in warehouses; finally apprehending two drugged out burglars inside a warehouse.

Malloy has to shoot one of two robbery suspects, then the officers counsel a young woman in a bad neighborhood not to hang around (she is later kidnapped by two men claiming to fix her car), the LAPD's Air-Ten helicopter is used to catch the kidnappers (who already had outstanding kidnapping warrants), find a "mover" (burglar) whose partner hides in a freezer, and the officers visit an apartment on a domestic dispute complaint and find another woman with severe injuries but the couple insists nothing is going on, later arresting the husband on domestic violence charges after the woman's mother calls the police back to the apartment after the woman's husband beats their daughter.

Malloy celebrates his birthday by having to let Reed drive 1-Adam-12 (due to Malloy allowing his driver's license to expire) and is nervous about his young partner driving the car. Calls include a bank robbery reported by the Bank robber, a burglary involving several neighbors, an abandoned baby, a suicidal wife who killed her husband on their 22nd wedding anniversary, and a drug dealer selling his wares out of an ice cream truck.

After beginning the search for a well known suspect who just stole a 600-pound offset printing press, Reed and Malloy try to convince an 85-year-old man to leave the soon-to-be demolished apartment building where he's resided alone for 27 years. Afterward, they pull over a very unusual vehicle, and chase a delivery truck to the end of an unfinished bridge.

Malloy and Reed are called to a riding stable run by retired actor Slim Berkeley. The owner is careless about trusting people and has $100 and a gold belt buckle stolen. Because of a criminal record in New York his young assistant runs, but when searched nothing is found. A call to a phone booth where the man inside is being attacked leads to a drug arrest and sore jaw for Reed. Reed spots a robbery at a drive-in resulting in a shoot-out.

Malloy and Reed investigate a series of safe jobs, which all seem to tie in with a retired safecracker who is taking care of his orphaned niece and nephew, and after a "tip" from him, finds the niece and nephew practicing his old tricks on another safe. The officers also investigate a woman whose baby was held hostage by her cousin and forcing her to meet and steal from other men, after which the officers arrest the cousin and rescue the baby.

Malloy and Reed investigate an extortion racket against a group of Jewish Holocaust survivors, with the owner of a dry cleaners willing to testify but others not out of fear of retribution. The officers return to handle the owner's panel truck being set ablaze and later the owner is physically assaulted. Malloy and Reed capture both suspects. Other incidents involved a robbery at a bar (the perps escaped initially, but are later captured after a shootout), and a drunk man owed back pay by a dockmaster threatens to dump his boat onto dry land from a crane unless he's paid.

Police "buff" Jennings Thornton, a thorn in the side for Malloy and Reed, intervenes in a drunk driving case, runs down a shooter after a robbery (and nearly getting Reed killed), and is finally arrested himself for falsely arresting two teenage boys for stealing mag wheels that were actually legally bought. Another case involves a woman who stole an expensive ring from a store, leaving a cheap one in return; the suspect is later arrested during a parking lot dispute and the ring is found on her during a search

Malloy and Reed investigate a robbery in a store run by a group of "grandmothers", who sell small homemade items, then later return the money. The suspect later robs an antique shop but is captured when he returns to the first store to attempt another robbery, and the officers purchase some items from the "grandmothers". Other incidents include a high-speed chase of three robbery suspects, who are captured with the help of Sgt. MacDonald, and a priest stopped for a traffic violation who wants to have a drug dealer arrested for selling him marijuana.

The radical Robin Saydo on the loose, tied into a number of bombings. Reed spots him and Saydo is arrested by D.A. Paul Ryan. Other calls include an abandoned police cruiser which turned out to be a lone policeman on a foot pursuit capturing a drug suspect, and retired security officer Fred Tibbles assists the officers in breaking up a truck theft ring which took the trucks but not the merchandise within them.

Note: This episode begins a crossover with The D.A. that concludes on "The People vs. Robin Saydo".

1-Adam-12 is back on the streets after routine maintenance, but the radio isn't working properly. During an armed robbery involving two suspects, Reed captures one while Malloy takes off in pursuit of the other one through Griffith Park and loses control of the car, and it rolls into an embankment hidden from the road, with Malloy suffering severe internal bleeding and a broken leg. All available units are called in to search for Malloy, who has to watch helplessly while a suspect hiding in the park takes his shotgun (which Malloy was using as a splint for his leg) and sidearm, and tears off the radio microphone leaving only leaving the wires. Malloy uses the wires to send a signal for help, which Reed picks up and is able to rescue his partner.

A man named "The Ferret" is vandalizing a manufacturing plant due to their poor record on ecology, and escapes Reed easily on foot pursuit. A reporter catches Reed in an unflattering light after the escape and plasters him over the front page. Reed is redeemed when he catches the Ferret when he returns later to the same plant and dumps a bucket of waste in the lobby. Other calls include a man whose pregnant wife fell into a coma after eating mud given to her by a voodoo priest, resulting in her baby boy being stillborn (when the officers confront the priest, he puts a mojo hex on Reed), and an elderly lady pulled over for a traffic violation who thinks the policemen are gas station attendants.

Truancy is on the rise in the district and Reed has a plan to pick up truants on the street, which was approved after a garage break-in by two truants. Results show a drop in crimes committed by truants, in one case two truants were stopped by the police and were implicated in a burglary, and one of the two truants involved in the garage break-in is brought in on another incident. Other incidents include arresting two heroin smugglers who hid the stash in their car's gas tank, which leaked some of the contraband making the car stall, and stop car thieves from stripping parts to build a dune buggy. Starting with this episode, Officer Ed Wells is promoted to Police Officer III (just under Malloy's rank of Police Officer III+1).

Malloy and Reed are sent to assist the Los Angeles County Sheriff's Department with transporting a prisoner from Malibu to Los Angeles for outstanding traffic warrants. During the trip, the prisoner reveals he is also a witness in a mob murder and a hit has been ordered on him. Suddenly, the cruiser is ambushed on a rural road, a tire is shot out, and they crash on a dirt road out of radio range. Reed is captured by hitmen attempting to get assistance, but Malloy and the prisoner steal the hitmen's car to get to a phone. The LAPD sends a police helicopter to search for Reed, who ends up overpowering the hit men and are captured.

Sgt. MacDonald's anniversary is coming up and the officers have limited funds to spend on a gift, which is a bottle of champagne, but when the officers pick it up, the owner of the liquor store was shot in an attempted robbery. Malloy and Reed later find the robber dead in a park from a gunshot wound inflicted by the owner. Other incidents include a paralyzed ex-wrestler tearing up a bar, a man driving suspiciously turns out to be the proud owner of several traffic tickets in a 24 hour period, a used car dealer trying to take advantage of a Mexican customer who speaks little English, and two camper thieves pushing a truck with a camper that is too small for the truck bed.

Over the course of their shift, Malloy and Reed deal with a racist gas station owner who is tired of being the victim of repeated robberies. When they catch the suspect, supposedly a black man, they find he is actually just an equally-racist white man in blackface. Other calls include a hitchhiker who extorts money from drivers she leaves in embarrassing situations, and a drunk who is seeing pink elephants.

A phony prowler call results in shots being fired at Malloy and Reed. Shots ring out again when the officers head to the airport to transport a blood donor. The suspect is a known check bouncer, and Reed's wife gets a disturbing phone call. Later Reed heads home and meets an acquaintance who just happens to be driving the same car as the shooting suspect. Other cases include a suicidal man who tries to incinerate himself with gasoline, and a wino who is nearly shot by Reed.

Officer Art McCall returns from eight years on disability and rides with Malloy and Reed to see how much has changed in law enforcement. McCall soon learns exactly how much has changed when he tries illegal techniques to help a young woman with her ex-con husband, fails to Mirandize a boy after arresting him for robbery, and screws up an arrest of a gun-carrying man who later plants a bomb in his ex-wife's car, which requires Malloy to dress down the veteran officer on his use of antiquated (and illegal) police procedures.

Malloy and Reed find a girl who was raped and left for dead in the hills but was actually alive and identified her attacker's car as a red Porsche. Malloy spots the suspect car picking up another girl and gives chase, only to have the suspect dump the girl on the street and the officer loses the car. Later the girl's mother finds drugs in the laundry and determine she was selling and the "rapist" was her supplier, while the real rapist is caught when he checked out of the hospital after being hit by his victim's heavy purse. The officers also handle a robbery at a construction yard foiled by police scouts.

Cases include a woman whose purse was robbed after two men bumped her car while on the road, then are captured along with the loot when a citizen complains about loud noise coming from their lair. A broken-down car leads to a meeting between the car's owner and a counterfeiter, and a fight in a fast-food restaurant results in an arrest of one of the combatants on outstanding warrants.

A disturbance call leads the officers to a nightclub where a singer named Kathy is strung out on drugs, and clings to Reed on the way to the hospital, telling him someone is trying to kill her and give her drugs. Narcotic detectives decide to assign Reed undercover as an AWOL soldier with a large stash of heroin to sell. Reed makes a deal, but Kathy blows his cover, and Malloy saves his partner from being killed and helps bring down the dealers.

Malloy and Reed deal with a woman who thinks she has a rattlesnake in her luggage, an out-of-town traffic violator, and a bar brawl, all while tackling armored truck robbers whose attacks have been predicted in advance by an informant.

Malloy is told that the best player on the recreational league basketball team he coaches has begun using narcotics again, which he flatly denies despite evidence to the contrary. He and Reed also search for a hit-and-run driver who struck a child, and pull over a driver with a seemingly disrespectful and wanted passenger.

Malloy and Reed investigate the ransacking of a college football locker room and uncover a controversial performance enhancing drug program. They also investigate suspicious parents who backtrack after their maid reports their baby as missing, apprehend a reported prowler who is then suspiciously let into the home by the female accuser and engage in a bullet-riddled high speed chase through a residential area.

A young girl from Chinatown is ordered by her father to withhold information from Malloy and Reed regarding her boyfriend, an undercover cop left in a coma after investigating a potential attack on a Chinese elders' association. Meanwhile, the officers also encounter a middle-aged marijuana user and a cross-dressing criminal who leads them to a counterfeit money ring while trying to pay his lawyer.

On temporary assignment at LAX, Reed and Malloy have to save a stewardess who is taken hostage inside a lounge by a man desperately trying to get the attention of a television producer. Afterward, they go undercover as rental car employees to intercept a large narcotics delivery from Toledo, and then try to identify and apprehend a rape suspect before he's able to escape on a flight.

Malloy tries to prove Sgt. MacDonald's innocence when Mac accidentally hits and kills a jaywalker while driving his police cruiser. Every witness on the sidewalk claims she was in the crosswalk, and the burglary suspect MacDonald is transporting is unmotivated to testify on his behalf. The truth proves to be far more complicated than the officers realized.

Malloy and Reed work to curtail the rise in illegal street racing by working with the leaders of rival racing clubs and obtaining the legitimate use of a drag strip through a race promoter. Their work is threatened, along with an anticipated race between Reed and Officer Wells, when one of the racers resorts to sabotage.

Malloy and Reed search for a six-year-old boy who was apparently abducted while walking home from school, and later fear that an elderly witness's wildly inaccurate account may actually pertain to a different crime. They also respond to a barking dog complaint and become suspicious of the dog's owner, mediate a domestic dispute caused by a husband's obsession with watching football, respond to a very creative college prank and pursue armed robbery suspects through a crowded train depot with the aid of a police helicopter.

Reed becomes preoccupied with the well being of a friend, an electrical engineer by profession, who has just qualified as a reserve police officer and has the bad luck of drawing Officer Wells as his partner. On patrol, Reed and Malloy help out a group of distrusting young adults who are planning to illegally camp in a public park after a rock concert, pull over a young couple in a stolen car and aid wells and the reservist in the foot chase of a heavily armed man who has been coercing innocent strangers into committing bank robberies.

A series of purse snatchings involving motorcyclists frustrates the LAPD, as they cannot follow them down the off-road trails they take. Reed holds a community meeting with the various motorcycle clubs, and the leader of one club challenges Malloy to a dirt bike race. Reed teaches Malloy how to ride a dirt bike, and while Malloy loses the race, he gains the respect of the club's leader, who helps them apprehend the suspects by blocking their escape route.

Malloy finds himself attracted to the new girl in the steno pool, and decides to ask her on a date after learning she's Officer Wells' 25-year-old niece. Out on patrol, he and Reed investigate a report of a prowler in a heavily wooded neighborhood, make a deal with a flower vendor before booking him for unpaid tickets, engage in a high-speed pursuit with a green corvette and investigate a suspicious gardener.

Malloy and Reed are patrolling the outskirts of Los Angeles when a girl on horseback alerts them to a small plane that landed in a secluded area. When the officers investigate, they see a pickup truck fleeing and the plane trying to take off; though they stop the plane, they have no proof the pilot did anything. Malloy and Reed later learn from the DEA that a Mexican cartel is behind the landings, with the pilot instructed to play dumb if caught. The officers find the pilot and trace the pickup truck's location, and the truck is followed to the landing site, where the smuggler and the pilot are arrested.

Reed and Malloy rush an 8-year old to Rampart Emergency Hospital, where he is diagnosed with diabetes. Scared of the hospital, Jimmy runs off, and it's up to Reed and Malloy to find him before he goes into a diabetic coma. Elsewhere, Malloy's new girlfriend, Cathy, mans a hospital telephone hotline. Sherry, a 15-year old junkie, is threatening suicide to escape her troubled life. Malloy and Reed need to find her fast, before she OD's.

Officer Charlie Burnside pulls a prank on Officer Albert Porter, a friend of Reed's. Porter, who does not find the prank funny, informs Reed that Burnside is frequently "badge-heavy" (rough) with his suspects. After dealing with an inept would-be robber, Malloy and Reed observe Burnside choking a suspect. Reed reports the incident, but nothing is done by the Captain because the victim would not admit Burnside was the aggressor. Burnside turns cocky on Reed saying he has "an ace in the hole" and that Reed was mad about the prank he pulled on Porter, but it is later revealed that Burnside got to one of the robbers, placing him under investigation. At the end of watch, Burnside tries intimidating Reed, then tries brushing his intimidation off as a joke when he realizes the other officers are against him; when they all walk out, Burnside resigns.

A hotel janitor (and wino) named Harry witnesses a murder in a hotel room, but refuses to talk until Reed shows him compassion and respect, both of which are lacking from his family and friends, but his testimony is clouded by his alcoholic past. Malloy relives his childhood by telling the story of his chaperoning a junior high dance.

During Malloy's birthday, he lets Reed know he does not enjoy surprise parties, but becomes increasingly suspicious and believes the others are actually planning a surprise party, much to his chagrin; it is soon revealed that is not the case. Meanwhile, Sgt. MacDonald warns the officers about a rash of robberies using milk crates to break store windows; during a routine traffic stop, Reed notices a milk crate in the back of a car and surreptitiously marks it for identification later, and the thief is apprehended later using the same milk crate. Calls include a backup call for a jewelry store robbery when the officers pull over the owner of said store for DUI, an embarrassed male purse snatching victim inside a negligee shop, a phony gas station worker at a closed gas station, a shootout in the police garage between the entire station and a drunk suspect officers failed to handcuff, and Officer Wells capturing a B&E suspect based on a hunch by Malloy.

A World War II survivor and tailor shop owner sets an ambush for an unidentified intruder when Malloy and Reed intervene. R&I determines the owner is clean and emigrated to the U.S. seventeen years earlier from Eastern Europe. The officers speak with a local priest who knows the owner, who complains to Sgt. MacDonald about what he feels is the officers' interference. Later, shots are fired at the shop, and the officers find a wounded intruder with no one else in the shop. Malloy and Reed find the owner with the priest, who informs them that the intruder is a former Nazi soldier who killed his relative during the war.

Malloy and Reed encounter an armed private investigator from out of state, who is in Los Angeles to find a bail jumper. Later the PI is in the middle of an altercation with two black men, one of which is injured; the PI claims the men tried to rob him, but the men tell a different story, and Sgt. MacDonald orders the PI arrested. The PI is found roughing up the bail jumper and is arrested. Calls include an elderly man wanting a group of cars driven by hippies ticketed for illegal parking, and a woman who demands the officers ticket her husband's car because he refuses to replace the balding tires on it.

Malloy and Reed have to wear their long-sleeved uniforms despite a hot forecast, then learn they could have changed to short sleeves but missed the radio notification. Calls include the search for a bicycle pump that contains drugs, a woman experiencing withdrawal symptoms with the dealer and the pump up the street, a man complaining about his grass being trampled during his neighbor's yard sale (which had stolen property taken by the neighbor "on consignment") leads to the discovery of the burglar, who then provides a tip on a murder suspect.

Malloy and Reed are called to a hotel to stop a woman's suicide attempt; while there, they learn of a parolee there who refuses to speak with the woman because he thinks someone from the mob is after him. Later the officers are called back to the hotel because the manager wants the parolee evicted; another call to the hotel leads to shots fired from the parolee, who was having delusions the mob was after him. In another case, the officers offer assistance to a man whose extremely damaged car simply needed a tire change; the man and his car are later the suspects in a robbery, and detectives arrest the man with the officers' help.

Malloy's old landlady, Mrs. O'Brien, has her purse stolen and refuses to leave the station until her case is settled. Mrs. O'Brien resorts to other means, including hounding detectives and setting up a picket line to vent her frustrations. Malloy makes connection between her theft and a string of purse snatchings involving social security checks, and a decoy leads to the end of the theft ring. Calls include two suspicious men and a pursuit involving them, and a homicide where candy wrappers and tire tracks from the pursuit suspects are found.

Reed spreads his flu to several other officers, leaving the station undermanned. Calls include a shootout with a rifle-toting bookie, an argument between a storekeeper and a customer over a cantaloupe during an unrelated traffic stop, Reed locating a burglar after seeing a flashlight inside a store, and a teenager evading Reed in a foot pursuit. Due to the understaffing situation, Malloy and Reed are asked to do double shifts, and Malloy tickets a woman for turning right at a red without stopping. Later, Sgt. MacDonald assigns them to drive around a police commissioner for the night; the commissioner is actually the woman Malloy ticketed.

Malloy and Reed arrest a seemingly less-fortunate woman for shoplifting items for her baby, but she escapes from custody during a disruption at the station; the officers later learn the woman and her husband actually stole the baby, as they could not have one of their own. After finding the woman at a landlord-tenant dispute, they learn the woman's husband stole his car, and that the manager supposedly made an extortion call demanding $2,000 for the baby. The officers pursue and eventually catch the husband at a rail yard. Another call results in Reed briefly being held at gunpoint by a burglary suspect; Reed manages to trick the suspect and signal Malloy for help.

Malloy and Reed are given an older cruiser with 300 miles to go until retirement. They quickly learn the car is extremely unreliable and barely works: the accelerator surges, the glove compartment door constantly drops on Reed's knees, the water hose breaks while they are sneaking up on a prowler suspect (actually just a man who once lived there), their malfunctioning taillights prevent them from writing a ticket to a citizen whose car had the same problem, the distributor cap fails when trying to respond to another call, and finally, after capturing a pursuit suspect, the car's brakes fail and the unmanned car totals itself on a light pole. Another call regarding a truck loading up at a warehouse leads to the arrest of a large group of organized burglars after Malloy notices a slight discrepancy in their otherwise foolproof plan.

Malloy and Reed pull over a car on a routine traffic stop and are taken hostage by two robbers escaping from their heist. The officers have to use all their skills to escape the situation.

Reed spends a Saturday night talking about buying a used car, during the watch the officers handle a possible DUI but the driver passes the field sobriety tests, a shooting during which a man kills his recently paroled son-in-law, a car stripper, trick a man into revealing his name after pulling him over for speeding and finding the car has over $900 of unpaid tickets, and two beatings at motels.

Reed spends an evening on the firing range, then stops by an all-night grocery store. When Reed leaves, a man approaches him as if he knew him, then points out another man in a green Beetle holding a gun on the officer. Reed drops his groceries, shoves the man, jumps and fires at the Beetle driver, hitting the car, but the man in the Beetle shoots his accomplice. The grocer swears he only heard one shot, and the accomplice gives a dying declaration that Reed was trigger-happy and shot him, leading to Reed's suspension. Malloy and his by-the-book replacement partner locate the green Beetle (now yellow) after going through numerous DMV checks and locate the other man, exonerating Reed.

Malloy wins $10,000 in a women's shampoo naming contest and is stampeded by people telling him what he should do with the money. Calls include an elderly male tenant complaining that a new elderly female tenant's Irish music is too loud, a sniper wreaking havoc until he is shot trying to escape in a car, a reported theft turned out to be a broke man whose three wives stripped the expensive house he was in clean except for the stolen items, and a wino is killed by another wino for his new tennis shoes.

Malloy and Reed spot a runaway young boy hiding in the woods and prepare to take him home, then respond to his address for a disturbance and find his mother and step-father quiet. They return a second time with the couple throwing things at each other and break it up. A third call to the same address forces the officers to send the husband to his sister's house, but he returns to the apartment and when he does, shots ring out just as the officers arrive for the fourth time. Calls include a motorist encountering a girl who offers him drugs, a man trying to break into his own truck after his dog locked him out, and a drunk bicycle thief.

Malloy and Reed are stunned to discover that the driver who led them on a high-speed chase is the son of Sgt. MacDonald, and Malloy takes it upon himself to help his boss figure out why the young man is acting out. In the meantime, they investigate a possible burglary in progress at an apartment building, mediate a dispute at a park over an elderly woman feeding ducks, respond to a call of two armed men fighting over a woman and deal with a wino who is attempting to direct traffic at a busy intersection.

Reed loses a case against a young car thief in juvenile court, who later dies in high-speed pursuit. A girl's boyfriend dies from a heroin "hot shot", she buys drugs from the supplier and provides the serial number of the $10 bill she used to buy them. An elderly woman insists on being arrested rather than ticketed for a traffic violation.
