It is 1898. In the New Mexico wilderness, Daniel Plainview (Daniel Day-Lewis) works his silver mine. When he breaks his leg
when he finally finds the silver ore, he drags himself to town to sell it. He hires a crew, including a man caring for an
infant son. When the silver mine plays out, Plainview discovers oil in the mine. He builds a pump and recreates himself as an
oil man. The young father dies in a drilling accident. Planview adopts the young boy as his own and names him H.W. Nine years
later, Plainview is a successful if still somewhat minor oil man. He has several productive wells around New Mexico and, with
H.W. (Dillon Freasier), travels the state to buy the drilling rights to private property.
