The Hole in the Wall.

When spiritualist Madame Mysteria is killed in a train wreck, her three associates decide to replace her instead of declaring her dead. One of them, the Fox, calls on Jean Oliver, who he knew from prison. Jean was serving time after being framed by her former employer, Mrs. Ramsey, for a theft just to keep her and her son, Donald Ramsey, from marrying. Jean agrees to the crooks' scheme providing that they help her kidnap the baby that belongs to Donald and the woman that his mother had him marry.
