L.A. private eye Sam Black, who lives with his half-brother, Andrew, travels to the Bahamas to assist Abigail Marx, a woman who believes her husband is stealing money from their company. Black finds the proof but in the process is shot by Harry Marx. While recuperating in a Bahamas hospital he meets a beautiful widow, also from L.A., named Martha Greenwood. Back in California, Black reunites with Martha who tells him the money left her by her late husband is controlled by unscrupulous business manager, Robert Chandler. Together Black and Martha devise a scheme to transfer the money away from Chandler's control. Black carries out his part of this scheme but then discovers that Martha has plans of her own.—dinky-4 of Minneapolis
