Racecar driver Bill Foster (Dick Purcell) has the talent to collect racing trophies, but his reckless stunts on the track get him banned from the racing association altogether. Hitting the road with his loyal sidekick, mechanic Stub Wilson (vaudeville veteran Charley Foy), Bill crashes into a bus owned by Neeley Transport. Bill is determined to sock Neeley's president in the nose because of the damage to his race car, only to discover that the president is the attractive Jerry Neeley (Beverly Roberts) a woman immune to Bill's charms. Bill goes to work for Tommy Burnell (Donald Briggs), the owner of a rival bus company that is sabotaging Neeley Transport. Once Bill learns he's working for the wrong side, he goes out of his way to help Jerry save her company. This B-movie classic serves up an entire movie serial's worth of thrills and chills in one streamlined entertainment machine, ably delivered by a cast and crew of true show-business veterans (including radio star Gloria Blondell, sister of Joan).
