Bill "Stoker" Thompson (Robert Ryan) is a 35-year-old has-been boxer about to take on an opponent at the fictional Paradise City Arena. His wife, Julie (Audrey Totter), fears that this fight may be his last and wants him to forfeit the match. Tiny (George Tobias), Stoker's manager, is sure he will continue to lose fights, so he takes money for a "dive" from a mobster, but is so certain of Stoker's failure that he does not inform the boxer of the set-up.
