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.
While Big Daddy Bennett and Dr. Schultz discuss terms, Django is given a tour of the plantation by a house slave. During the tour, he asks the slave if three brothers by the name of Brittle are employed at the plantation. The slave is confused but says that three brothers named Schaffer were recently employed. Django spies one of the brothers overseeing the field slaves and another brother who is about to whip a slave for breaking eggs. Django has flashbacks to when the Brittles whipped Broomhilda while Django pleaded with them to not do it
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. The crack of the whip. This foreshadows that their time is running out and that bloodshed will ensue.
