Tonka

Inspired by actual events, Tonka tells the story of the only survivor of the famed 7th Calvary who fought at Custer's Last Stand. Sal Mineo stars as White Bull, a young Indian brave who 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. Tonka finally finds a home with Capt. Keogh and the 7th Calvary, and in 1876, rides into the Battle of the Little Big Horn with General Armstrong Custer. (official distributor synopsis)
