When an old man wearing a strange-looking belt is found dead of natural causes, fraud is suspected and the case is turned over to major frauds division. Investigation leads to a Dr. Gantman, whose useless treatment of a blind seven-year-old girl with a pituitary tumor is preventing its timely surgical removal. A break comes when a television repairman, who makes "electro-charged oscillator belts" for the doctor, is arrested for bookmaking and is willing to testify against him. The bookie isn't needed after a courtroom demonstration by the doctor results in the doctor's undoing.
