Young Indian brave White Bull captures and tames a wild stallion and names him Tonka. But when White Bull's cruel cousin claims Tonka for his own and mistreats the horse, White Bull sets him free.

Trivia, insights & behind the scenes
Disney killed so many horses filming the Little Big Horn sequence that the ASPCA intervened and new animal welfare regulations were created. The 'no animals were harmed' credit exists partly because of this movie.
The real Tonka/Comanche was taxidermied and still lives at the University of Kansas—he's the only 'survivor' of Little Big Horn who became a museum exhibit. The movie actually undersold the weirdness.
