 Cavalry Lieutenant Can Elliott (George Montgomery) is ordered to bring in Seminole Indian chief Black Cat (Steven Ritch as Steve Ritch), who is leading his tribe in a campaign of terror and bloodshed. Black Cat kidnaps Susan Hannah (Karin Booth), daughter of Colonel Hannah (Howard Wright) and the girl Cam loves, planning to trade her to renegade white men for guns. Cam pursues the Seminoles, and after a bloody battle in which his small force kills hundred of Seminoles with avalanche and fire, forces Black Cat s surrender.
