Jean Oliver falls in love with a wealthy young man, and his mother, Mrs. Ramsey, sees to it that she is sent to prison on a trumped-up charge. Time passes. Jean is released from stir and throws in with a band of phony spiritualists, donning the robes of Madame Mystera, a crook recently killed in an accident on the elevated. Jean quickly proposes that her new companions in crime kidnap the granddaughter of Mrs. Ramsey and hold the child for ransom. The child is taken, but the police arrest the gang. The Fox, crafty leader of the spiritualists, is the only one who knows the whereabouts of the missing child, however, and he trades this information for immunity and a statement from Mrs. Ramsey that Jean had not in fact committed the crime for which she was sent to jail. Jean is freed and reunited with Gordon Grant, her childhood sweetheart, a reporter who has accompanied the police in the raid on the gang.
