According to legend, whoever sees the dog three times dies. When a Wall Street financier, who is about to come under indictment for embezzlement, sees the dog three times and then falls off a cliff. Marcie is quick to investigate the case. She soon finds that many of the man's acquaintances are happy to see him dead, and it soon becomes obvious to Marcie that determining if he died due to human agency or the curse of the "Black Dog" will not be easy.
