Marbleface is a an ex-prize fighter who becomes a fugitive after a failed robbery attempt lands him on the wrong side of the law. He’d almost been middleweight champion of the world, but then his heart went bad. So he trains himself to complete nerve control – he takes up poker as a living – he gets trapped into an escapade from which his victim’s daughter rescues him. With a bum ticker, Marbleface believes his days are numbered and sets out to reform, landing himself in the town of Piegun where he becomes the town’s hero. He stays honest and eventually finds himself well again and able to settle down with the girl he loves.
