From the Academy-Award winning film, Django Unchained.

In 1858 Texas, brothers Ace and Dicky Speck drive a group of shackled black slaves on foot. Among them is Django, sold off and separated from his wife Broomhilda von Shaft, a house slave who speaks German and English. They are stopped by Dr. King Schultz, a German dentist-turned-bounty hunter seeking to buy Django for his knowledge of the three outlaw Brittle brothers, overseers at the plantation of Django's previous owner and for whom Schultz has a warrant. When Ace refuses to sell Django to Schultz and levels his gun at him, Schultz kills him and shoots Dicky's horse in order to pin him to the ground. Schultz insists on paying a fair price for Django before leaving the other slaves to kill Dicky. Schultz offers Django his freedom and $75 in exchange for help tracking down the Brittles.

Schultz and Django concoct a plan to buy a Mandingo fighting slave from Calvin Candie, owner of Candieland Plantation and Broomhilda for a token sum. On the way to the plantation, Django witnesses Candie order his slave trackers' dogs to maul to death a runaway slave D'Artagnan.

After his ruse is discovered and Dr. Schultz is killed, Django is sent to be work in a limestone quarry for the rest of his life, but he escapes and returns to Candieland to avenge Dr. Schultz and D'Artangan. He ambushes the slave trackers.

Tarantino uses the plot device of actors doing something in rhythm like the ticking of a clock. This foreshadows that their time is running out and that bloodshed will ensue.
