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 and wagon train boss Tulsa are on to the nefarious schemes of Rance Rankin and Ace Devlin, getting words of warning through to Portico, the Son of Geronimo. 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."
