Joe Palooka (Joe Kirkwood Jr.) is the heavy weight boxing champ and is willing to defend the title against all comers. Of course there are some shady characters who would rather just buy the title, but since Joe and his manager Knobby Walsh (Leon Errol) aren't selling they come up with a scheme to take a cut of Joe's profits by tying up all the venues and rival fighters in exclusive contracts. So when they hear Knobby and Joe are off to visit the tiny town of West Wokkington Falls they figure they must have a bout planned and hustle to tie up the town and local strongman Humphrey Pennyworth.
