"Burn-em-Up" (sometimes with hyphens, sometimes not) Barnes is a race car driver who comes to the aid of bus line owner Marjorie Temple (Lola Lane, Deadline at Dawn) when a gang of crooks go after supposedly worthless land she owns. Helping Barnes is his teenaged buddy, Bobby Riley (Frankie Darro, The Phantom Empire). Also in the cast was Jason Robards, Sr. (who was billed just as Jason Robarts because his son -- being twelve -- was not yet Jason Robards.)
A lot of cars. A lot of racing. A lot of cliffhangers.
