Mannix almost loses Peggy when he tells her that he suspects her new boyfriend, Floyd Brown, of being the key man in the theft of forty-five cartons of morphine. Caught between her loyalty to Mannix and her love for Brown, Peggy refuses to listen to Mannix but later places her life in danger when she confronts Brown with the accusation.

Mannix is left holding the bag when he's hired by Pete Neal, a man he knows, to protect a man with $25,000 that they both claim isn't stolen. Neal is killed, and Neal's body, the man, and the money disappear.
