Monahan wants someone to examine a body that he thinks is involved in ‘smuggling' gems, a woman about to be autopsied is surprisingly found to be alive and Dr. Quincy is nowhere to be found. In his place is the brilliant, strict and feared Dr. Hiro.

On his way to a Forensic Pathologist convention in Sacramento, the Sheriff of a small town stops Quincy on the road. He was trying to stay awake by sticking his head out of the window. The Sheriff decides to put Quincy in jail for his own good. That night a fire starts in the cells and four men die. The towns' authorities call all the deaths accidental but Quincy, doing some of the autopsies to help the local Dr. is convinced that one of the victims was murdered.

Dr. Asten's niece is involved in a car accident while drunk and it is up to Quincy to try and establish whether she was the driver of the car or whether it was her friend, who died in the crash, who was driving. Asten gets Quincy to swap jobs with him for a day so that he can find out how hard it is to run the place.

Quincy investigates a plane crash at sea and discovers that most of the victims died needlessly.

A man is knocked down and killed by a drunk driver. Quincy is outraged to discover that the killer is likely to get away with a light sentence and tries to change things. His digging uncovers much more than he, and the prosecutor, could ever have expected.

Dr. Asten asks Quincy to stop of on his way to his fishing holiday to do an autopsy on a young boy. The coroner in the area wants back up evidence to help him close down the foster child home that was looking after the boy and other children. To help out one boy Emily and Quincy get the local authorities to try out a new scheme. The idea of this scheme is that a qualified therapist lives with the troubled family to try and stop any flashpoints from occurring, hoping that this will then enable the family to be able to live happily together.
