The Shakedown (1929)

Dave Roberts is a professional boxer better at losing in fixed matches than in knocking out his opponents. He turns up in towns and is part of a group who sets up corrupt boxing matches. Dave's life on the margins changes after he meets a mother and son.

As he begins to care for them, he ultimately has to decide whether to continue in his low-life ways or turn the tables on those who have been forcing him to participate in them.
