In Texas, in 1872, John Ellis, a former slave, and Sarah, a young orphan, founded New Babylon, a city of outcasts. Django arrives in the city on a search for the murderer of his family. There he finds his daughter Sarah, the sole survivor of the massacre.

Sarah makes a life-saving discovery for the finances of New Babylon: the city's basements are full of oil. With John, she pushes the door of the bank of Elmdale to finance a drill. They incur the wrath of Elizabeth Thurmann, the local potentate, who is preparing an ambush.

John, his sons, Django and Sarah travel to Nagadoches, where an old friend of John's might sell them a drill; alerted by Aaron, her protégé who infiltrated New Babylon, Elizabeth organises an attack.

Django uses a ruse to find out if Seymour is a traitor. He is supposed to accompany a bogus oil shipment to the north while another shipment is made to the south.

The revenge campaign against John continues; Elizabeth hires Leonard to kidnap Sarah; when Django finds out, he steps in and proposes a deal to Leonard.
