Plot

A patient of Chicago psychoanalyst Dr. Judd Stevens (Moore) is murdered after a session, stabbed while wearing a raincoat belonging to the doctor. Police detectives McGreavy (Steiger) and Angeli (Gould) investigate. McGreavy bitterly resents the doctor from a previous case in which Stevens’ testimony led to a cop killer being institutionalized rather than sent to prison.

The patient’s personal problems are in question until Stevens’ secretary is also found brutally murdered. Stevens realizes he is the murderer’s target, while the detectives treat him as their prime suspect.
