A sheltered heiress falls for a charming playboy and elopes with him, but soon discovers his gambling vice and mounting debts. As his lies deepen and those around them meet mysterious ends, she begins to suspect that her husband’s affection may conceal a deadly motive—and that she could be his next victim.
