Though the film is called Speed Devils, the only racetrack scenes occur at the very beginning of the picture. After cracking up during a race, the driver of the car (Paul Kelly) is advised to get into another line of work. Picking up on this, he and his buddy (Russell Hardie) open up a garage, only to be pounced upon by crooked politicians who want a chunk of the profits. The friend agrees to play ball with the crooks, but his partner balks at the idea. The villains then contrive to frame the reluctant man for a crime he didn't commit, and when this fails they lock our hero and his girlfriend (Marguerite Churchill) in a burning building. His pal comes to the rescue, and the two then team up to smash the corrupt politicos once and for all. Speed Devils was directed by former D. W. Griffith protégé Joseph Henaberry, who spent much of his talkie career on Poverty Row.
