Four friends go on a fishing trip but only three return. After an absence of four years, during which time he had been an amnesiac, the fourth man, Philip Vickers, returns home after regaining his memory. He tells of a "friend" who knocked him out, drugged him, and left him to die. Any one of the remaining men could be a suspect as Job Crandall, Bill Saul and Harry Bryce have all been interested in Philip's attractive 'widow', Angie. Unfortunately, Philip's return coincides with a murder and he becomes the main suspect. Angie joins forces with her husband to help solve the mystery and clear his name.
