In 1858 Texas, brothers Ace and Dicky Speck drive a group of shackled black slaves on foot. Among them is Django Freeman, sold off and separated from his wife Broomhilda von Shaft, a house slave raised in a German household who can understand and speak both German and English. The brothers are stopped by Dr. King Schultz, a German dentist-turned-bounty hunter seeking to buy Django for his knowledge of the Brittle brothers, Django's previous owners and a trio of outlaws for whom Schultz is carrying a warrant. When the suspicious Ace levels his gun at him, Schultz kills him with a fast draw and then Dicky's horse, which falls and crushes Dicky's leg. Schultz insists on paying Dicky a fair price for Django before leaving Dicky to the newly freed slaves, who kill him and follow the North Star to freedom. While visiting a town to collect on another bounty, Schultz offers Django his freedom and $75 in exchange for help tracking the Brittle brothers down.
