A game warden finds a fisherman dead in his boat. Although the man had died hours earlier there was a freshly hooked trout hooked on his fishing tackle and the sign of bruising on the back of the man's head. Blake learns that the man was a wife-beater who had threatened to divorce his wife and name a neighbor in the complaint.
A used car salesman's estranged wife shows up at his apartment and begs forgiveness. During their argument a gunman bursts into Victor's apartment and kills the pretty brunette. Blake discovers that the car the dead woman was driving was hot and decides to set a trap to capture the killer and break up the stolen car racket at the same time.
