 A mystery made mysterious by the writers via misleading clues, lack of cohesion and glaring loopholes begins when Speight (Kieron Moore) escapes after being found guilty of murder, and his wife, Thelma (Lois Maxwell), believes he is after her because she is in love with another man and has changed her name. Lawyer Bishop and friend (Paul Henreid), playing a hunch, finds Speight at the scene of the crime and learns he is after the real murderer and not his wife. They shift through several men as suspects, all of whom seem to know his wife rather well.
