Plot

Marjorie Temple, owner of a bus line and an apparently worthless plot of land, is set upon by rich oil speculators who know her land actually is worth millions. When they try to put her out of business for good, young race driver Burn 'em Up Barnes comes to her rescue - again and again and again.—Jim Beaver <jumblejim@prodigy.net>

Race-car driver "Burn-'em-Up" Barnes, adopts Bobbie Riley, the kid brother of his buddy George Riley, who was killed in a race. Barnes enters into a partnership in a bus transportation business with Marjorie Temple, whose life he saved in a battle with some gangsters. John Drummond, a scheming promoter, knows that land Marjorie has inherited lies atop valuable oil deposits and tries every method to wreck her business and force her to sell the land at a low price. Barnes takes desperate chances to raise money and keep Marjorie from losing her property in spite of the attempts made on his life.This, like most of the Mascot serials, is very visually interesting because of the many outdoor scenes that depict the L.A. area of the time.—Les Adams <longhorn1939@suddenlink.net>
