This case starts when a jockey (Douglas Walton) dies during a race after first giving a warning of his impending doom. As the case develops a rich business man and racehorse owner (Gene Lockhart) and the wife of an English major (Frieda Inescort) also die in mysterious circumstances.
The police suspect the businessman's niece Zalia (Virginia Bruce) though Philo isn't so sure and also has the hots for her. This is a neat little detective film involving the mysteries of hypnotism, double crossing and revenge.
