Daniel Plainview (Daniel Day-Lewis) is an embittered and self-centered man who begins his path to fortune as a silver prospector out in New Mexico before becoming an oilman, building his first, primitive oil well with a small crew. One of his workers is killed in an accident, and Plainview takes the man’s orphaned child, H. W., as his own; his initial successes allow him to expand his enterprise over the years, and he negotiates for new leases with a sales pitch that plays up his appearance as a family man through H. W. (Dillon Freasier).
One day, Plainview is approached by young Paul Sunday (Paul Dano), who, for a reward, tells him of an oil source on his family’s property in a small town called Little Boston. Plainview and H. W. travel there under the guise of hunting for quail and discover oil seeping to the surface. He offers to buy the land from Paul’s father Abel (David Willis) to much suspicion from Paul’s twin brother Eli (also played by Dano), who quickly establishes Plainview’s true interests; he demands more money for the deal, but he is brushed aside by Plainview with a much lower offer to his father. Daniel soon begins to lease nearly all the surrounding ranches and construction begins, allowing the hillside community to flourish from the flow of new wealth. Eli, who is a charismatic preacher and self-proclaimed faith healer, plans an expansion of his “Church of the Third Revelation.” He proposes to bless a newly-built oil derrick at its opening ceremony, but he is suddenly turned down when Plainview decides to bless the well himself. Not long thereafter, a worker is killed by a falling drill bit, and gas eruption causes H. W. to go deaf. When Eli finally demands the money promised to him, Daniel attacks him, mocking his faith and his inability to “heal” H. W. Eli returns home to take his anger out on his father, blaming him for selling the land at a greatly undervalued price.
The final scene features Eli, now ruined by poor investments lost to the Great Depression, visiting Plainview in his basement bowling alley. Eli discovers Plainview there, passed out on the floor, manages to awaken him, and Plainview immediately begins to drink more alcohol from a flask pulled from his pocket. Eli announces that the elder Bandy has died, leaving the grandson, and offers to partner with Daniel in order to drill the oil out from the old Bandy property, in exchange for a significant sum of money. But Daniel toys with his desperation by demanding that Eli first proclaim, “I am a false prophet, God is a superstition.” He then tells him that he has already drained the oil from Bandy’s land using the surrounding wells, and reveals that Eli’s brother Paul had years before sold the information to him about the oil on their land – exaggerating greatly the amount that he had paid him, in order to further torment Eli. Daniel announces that he had finally “beaten” Eli, but, unsatisfied with this psychological triumph, he chases and then beats a bewildered Eli to death with one of the bowling pins. His butler appears and approaches cautiously, while a tired Daniel ambiguously declares, “I’m finished!”
