O. Henry relates to his housekeeper the strange tale of Charles Spencer James (Gerald Mohr), a safecracker who by day poses as a doctor. One fateful night, a policeman stops James on his way home from a burglary to aid an upscale family that needs immediate medical attention. The husband lies paralyzed from a seizure, while his battered wife needs much more help than it appears. When "Doc" James learns there is $10,000 in cash to be had, only the paralyzed husband stands in the way.
