Two old, rich men like to wager among themselves on trivial matters for huge amounts. One of them, Williams, offers his friend a million dollars for his immortal soul. Blaine accepts but discovers that he is dying of cancer - frightened, he tries to buy his soul back. Williams holds out for more money, until it's too late - Blaine dies. Soulless, he comes back for his soul, shocking Williams into a heart attack...and the Devil comes to claim his due from both of them.
