The Unholy Four

Four friends go on a fishing trip but only three return. After an absence of four years, the fourth man, Philip Vickers, returns home an amnesiac. 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 are all 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.
