The self-styled son of Indian chief Geronimo gets himself involved with a gang of nasty whites in this typical low-budget 15 chapter serial, which benefitted from a great deal of footage from the the stock piles at Columbia Pictures. Jim Scott (Clayton Moore) and wagon train boss Tulsa (Bus Osborne) are on to the nefarious schemes of Rance Rankin (Marshall Reed) and Ace Devlin (John Crawford), getting words of warning through to Portico (Rodd Redwing), the Son of Genronimo. With Portico's help, the white renegades are finally destroyed in the serial's concluding chapter, "Peace Treaty." Moore, the future star of the television series The Lone Ranger, was here billed "Clay Moore." Usually cast as a villain, mustachioed Bud Osborne turned in a rare "good guy" performance in this serial.
Lin, un hombre malherido y perseguido por la policía encuentra acogida en casa de un sacerdote al que le cuenta su historia: cuando trabajaba en México, en un campo petrolífero, entregó a la policía a un hombre sospechoso de haber robado el dinero de las nóminas. Ese hombre murió después en extrañas circunstancias, y Lin, abrumado por un sentimiento de culpa, fue a trabajar al rancho de su viuda.
