It's 1920 and the start of Prohibition. Circumstances beyond his control find a young man, Huckabee Waller, involved in the death of a gangster in his hometown of New Orleans. Fearing repercussions from the gangster's associates, Huck hops a northbound freight and heads for the promise of Chicago. Expecting to make an honest living, he's surprised to find that he's arrived at the epicentre of crime, corruption, and commerce. Unable to find legitimate work, he gets mixed up in bare-knuckle fights run by the notorious North Side Gang. Reviving his skills as a club fighter, Huck quickly becomes a crowd favourite and makes enough to get by. When it becomes apparent to him that the gang is also heavily involved in running illegal whiskey, a very profitable enterprise, he's drawn into their world by the desire for more. As Huck starts running booze across the Canadian border for the North Side Gang and gets tangled up in Chicago's taxi wars, tensions between them and the South Side Gang flare up, and soon he's in the crosshairs of enforcer Al Capone. The smart thing to do would be to get out of Chicago - fast - that is if the life he wants to leave behind doesn't kill him first.
