It's been a long night of patrol for Malloy and Reed. Just as the two tired officers are headed to the station to turn in for the night, shots are fired at the patrol car. In the blink of an eye, Reed kills whom he believes was the gunman. Back at the station, Reed undergoes a night of intensive questioning from the captain and lieutenant, as part of the superior officers' investigation into the incident. In the end, the captain confides in Reed that his story is credible and the rookie officer will likely be allowed back on patrol upon the completion of the investigation.

Reed and Malloy make a routine traffic stop on a motorist. Before the NCIC check is completed, the dispatcher broadcasts a domestic dispute call in the two officers' patrol area; Reed and Malloy take the call and let the motorist go. Bad choice; the lieutenant soon calls the two errant officers in to scold them. Turns out the motorist had warrants out for his arrest on robbery and weapons charges. Malloy and Reed then come up with and carry out an ultimately successful plan to nab the wanted criminal.

Malloy and Reed respond to a call about a drug overdose and track the drugs to a 17-year-old who has barricaded himself in his room with a gun and threatens kill himself. They contend with a distraught mother and an overbearing father.

An impressionable Reed is taken in by the "cowboy cop" antics of fellow Officer Ed Wells (Gary Crosby), a wise guy who takes unnecessary and reckless risks to arrest suspects. At the station, Malloy loses his cool while talking to Wells because Wells' tactics endanger his life and others. Wells tries to play it down until his recklessness nearly catches up with him when he is shot in the shoulder by a psychotic sniper, and because of Wells' disobedience and foolishness Reed is also almost shot. Malloy and Reed are forced to rescue Wells and mastermind a way to end the standoff peacefully.
