Based on William Fay's short story The Disappearance of Dolan, Champ for a Day stars Alex Nicol as young pugilist George Wilson. Upon arriving in a small town for a scheduled bout, George discovers that his manager, Dolan, has vanished from sight. Also caught up in the mystery is Dolan's girlfriend Miss Gormley (Audrey Totter). Before long, George finds out that his missing manager was tied up with gangsters--and that George is expected to lose his next fight. How he extricates himself from this dilemma, and also solves his manager's disappearance, consumes the final four reels of this 90-minute Republic "special." The film's topnotch cast includes Harry Morgan as a trainer, Charles Winninger and Hope Emerson as the owners of a roadside hotel, and Joseph Wiseman as a wacko villain. ~ Hal Erickson, Rovi
