On his first tour of duty with Toronto, Sam becomes the Subject Officer in an investigation by the Special Investigations Unit. He remains one step ahead of them. On a trip to the red light district, he and his new coach officer learn that one of the hookers has been badly beaten by four men, but will not complain to the police. Sam begins his own investigation. When he discovers that the same men are responsible for the violent rape of a veteran police officer's niece, Sam formulates a plan to deal with them himself.
