One Wild Week: Pauline Hathaway is informed on her 18th birthday by the family lawyer that she will inherit half a million dollars, provided that her behavior meets with his approval; otherwise, the money will revert to her aunt. With new clothes Pauline sets out to visit her mother's friend, Mrs. Brewster. Framed en route by a pickpocket, she is sentenced to a reformatory for 30 days. In court, however, she has been seen by Bruce Reynolds, an amateur investigator and nephew of Mrs. Brewster who is convinced of her innocence.
