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.
The Monthly Film Bulletin wrote: "This confused and unconvincing murder mystery is so spattered with red herrings as to be almost incomprehensible. Paulette Goddard works hard; but for the most part the acting is little superior to the material."[5]
The New York Times wrote, "A THIRD-RATE British-made whodunit called The Unholy Four, featuring Paulette Goddard and a nondescript cast ... A few more fly-by-nights like this Lippert presentation, produced and written by Michael Carreras, and the still-shapely Miss Goddard may find herself collecting the pieces of a career."[6]
In British Sound Films: The Studio Years 1928โ1959David Quinlan rated the film as "average", writing: "Strength of character sees well-worn, fairly suspenseful thriller through."[9]
