Circumstantial evidence suggests that a murdered cop was supplementing his income as a blackmailer. Chief Ironside (Raymond Burr), an old friend of the dead man, is determined to prove otherwise. In the course of his investigation, Ironside reopens an unsolved homicide case in which the deceased officer's girlfriend Adrienne May (Jan Shepard) was a key player. Featured in the cast is Robert Alda, the father of future M*A*S*H star Alan Alda. ~ Hal Erickson, Rovi
