Custer's Last Stand (1936) - Rex Lease A 15 Chapter Movie Serial
When some men are attacked by Indians, a survivor obtains an Indian medicine arrow. An Indian tells Blade he has found gold but will not tell him where until he has that arrow. So Blade starts killing the survivors of the attack but fails to get the arrow. One of the men he kills is John Cardigan and Kit Cardigan (Rex Lease), a Scout for Custer, now starts looking for the killer of his father.
Custer's Last Stand is unique among all the serials. It has many more principal characters, each with their own story thread. It's all tied together by a quest for a ceremonial Indian arrow with coded directions to a cave of gold, but that's strictly a continuity device. The cave is never even found. Along the way there's a hero searching for his father's killer, a disgraced soldier battling alcoholism, a renegade Indian trying to foment a battle with the white settlers, an Indian girl with divided loyalties, an equally conflicted saloon owner, shoot-outs, fist-fights and large-scale battles, cameo appearances by Buffalo Bill, Calamity Jane and Wild Bill Hickok, and of course the climatic massacre at Little Big Horn. This is one brim-full serial!
