Dave Toma is about to begin a dangerous investigation of a gangland killing in which two citizens were killed by mistake when Inspector Spooner informs him he will be joined on the case by a university student observing police procedures. Student Larry Tapscott qualifies as a volunteer for the police departments field experience program and his request to observe Toma in action is approved by Spooner. Despite initial annoyance with the added responsibility Toma soon takes a liking to the youth whose interest in the case proves to be far more than academic.
