The thriller's heroine is Susy Hendrix, a blind
Greenwich housewife who becomes the target of three thugs searching for 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.
