Two men are killed. 30 years ago in college they were part of a group which was charged for the death of a fellow student in a test of courage. Charlie and Kaz want to protect the remaining three from the killer, but it seems the killer is among them. Helping Charlie and Kaz is a member of the bomb squad named Dutch. Though he's quite a specialist, Charlie discovers Dutch's could-get-dangerous illness - schizophrenia.

Charlie and Kaz get assigned to a delicate case: the murder of the commissioner's mistress. The commissioner has hired a killer to search for the videotape that shows him in a compromising position.
