Dan Malloy (Hoot Gibson) is a stampeder - a professional cowboy and skilled horseman who travels across Canada following the rodeo circuit. He competes in the popular Roman Races or Roman Standing Races where he stands on the backs of two horses like the ancient Romans, one foot on each horse, running full speed around the racetrack in a wild and exciting race against other Roman Race teams. As a Champion Roman Racer, Dan Malloy meets and falls in love with a French Canadian belle, Miss Marie LeFarge (Virginia Brown Faire). But her father (Clark Comstock) dislikes the flamboyant cowboy and stops the deepening romance. The father ends up mysteriously murdered, and Dan Malloy is accused of the crime. The real killer is a drifter and ex-con who has won the heart of LeFarge family's housemaid, a Canadian Indian maiden named Neenah, who keeps him hidden and unknown to the law.
