O'Brien is bent on vengeance as he tracks down the three men who brutally murdered his fiancee. He kills one and traces another to the Seventh Cavalry. There he finds the second man, Tucker, now a sergeant in the Army, and the third man, Jagger, a storekeeper. Before he can kill them,
however, all three are taken prisoner by Indians. Tucker gives up his life so the other two can escape, and Jagger rides off to warn General Custer (Millican) of an ambush. He is killed, allowing Bergen, his daughter, and O'Brien to carry on their romance with a clear conscience. Neatly scripted,
and featuring some of the best cavalry-Indian battle sequences ever put on film.
