This mystery thriller’s heroine is Susy Hendrix, a blind Greenwich Village housewife who becomes the target of three thugs searching for the heroin hidden in a doll, which her husband transported from Canada as a favor to a woman who since has been murdered. The trio tries to convince Susy her spouse has been implicated in the crime and the only way to protect him is to surrender the doll. More murder and mayhem ensue when she refuses, with the stage lights turned off for the final scene when Suzy levels the playing field by plunging her apartment into total darkness.
