Viveca Scott runs Beauty Mark, the cosmetics company whose products are in every woman's home. With sales dropping, she's counting on the miraculous new beauty cream created by her chief chemist to boost sales and overtake her rival, David Lang, but the chemist's assistant steals the formula. Scott attempts to negotiate with him but, in a rage, knocks him over the head with a heavy microscope, killing him. Her rival's secretary finds out and attempts to blackmail her, but the cosmetics queen's worst news is that the rumpled, redoubtable Lt. Columbo is on the case.
