It stars Tom Neal as a private detective named Russ Ashton and Pamela Blake as his secretary Susan Hart. Russ’s detective agency is floundering and about to go under; hungry for any assignment, he accepts an out of town job to guard jewelry at an overnight social affair. While he’s on assignment, his girlfriend, who is not suited for detective work, takes charge of the office and accepts a mysterious client, Mr. Moreland (Leonard Penn), who wants photographic evidence that his wife is cheating on him. He hands Susan a hatbox that he rigged with a “camera” inside. But, instead, the hatbox contains a gun, and Susan is flabbergasted when she unwittingly shoots Mrs. Moreland (Olga Andre). This gimmick used was inspired by a real-life murder case. Why Susan shoots a picture of Mrs. Moreland in the street seems odd, since she’s certainly not in an act of cheating (just one of many major plot holes). The DA arrests Susan, but Russ on his return brazenly acts to clear her name by trying to catch the real culprit with his loyal assistant Harvard (Allen Jenkins) and the help of the police. Jenkins is around for comic relief, as his dim-witted character spends most of his time gobbling down hamburgers from his girlfriend Veronica’s nearby hamburger joint.
