Gangster/gambler Jack La Rue tells boxer Kane Richmond to throw the fight, which he doesn't. La Rue takes a swing at Richmond, who responds and knocks him out. Richmond's manager, Monte Collins, tell him to get to Chicago, and keep out of sight, so Richmond takes the hobo route. At a jungle, after being serenaded by the jolly bindlestiff chorus and their monkey, he has to take to his heels, along with Frankie Darro. When they hit Chicago, Richmond begins training Darro at anti-fight Frances Grant's gym, while doing his best to stay out of sight.
It all sounds very unlikely, doesn't it? Richmond shows more screen charisma than I've seen him demonstrate in any of his other movies, but the occasional jarring detail derails the flow of the story. Fred 'Snowflake' Toones also has a role, and he sings in a voice totally unlike his normal screen voice.
