It's the U.S. Cavalry versus the Indians in this lively shoot-'em-up. Jess Remsberg (James Garner) is a ruggedly handsome scout, and Toller (Sidney Poitier) is a former trooper who makes a living breaking in horses. When their former commanding officer leads a group of raw recruits to a distant outpost, they're ambushed by Apaches -- and it's up to Remsberg and Toller to save the day.
