The mother of a family of real-estate swindlers and her boyfriend get caught and go to jail. Her son Sam gets his sister Constance to pose as the long-lost daughter of rich widow Mrs. Waldron, who has been driven to the edge of insanity over the disappearance of her daughter. However, Mrs. Waldron's secretary Laura Campbell doesn't believe for a minute that Constance is her employer's daughter, but holds her tongue because Mrs. Waldron's health begins to improve under Constance's care. By the time Constance's mother and boyfriend get out of jail, Constance is starting to re-think her part in the family's scheme to swindle the old woman.—[email protected]
