In the 1880s, believing that he has been swindled out of his inheritance, young Jet Cosgrave returns to Colton, Colorado. Eight years before, after Jet’s father died, lawyer Andrew Devlin presented a will leaving the Circle C Ranch to Jet’s uncle, Maj. Linton Cosgrave. Jet suspects that the will is phony, but having lost faith in legalities, hires nine mercenaries, led by Dude Rankin, to help him take the ranch by force.
