In the 1920s, after being forcibly relocated by the government, the people of the Osage Native American tribe see a reversal of fortunes when they discover that their new land in Oklahoma sits on huge reserves of oil.

Returning from WWI, Ernest Burkhart (Leonardo DiCaprio) is offered a job by his wealthy uncle (Robert De Niro), but the cattle baron’s benevolence has a hidden agenda: to gain control over the oil, no matter the cost. To that end, he steers the ambitious-but-dim Ernest to strike up a romance with tribeswoman Mollie (Lily Gladstone). As racial tensions rise, an ever-increasing number of Osage people are found dead under mysterious circumstances, eventually leading the fledgling Federal Bureau of Investigations to take an interest.

Epic, intimate and utterly absorbing despite its three-and-a-half-hour runtime, Martin Scorsese’s 26th film showcases the octogenarian director at his peak with his two long-term muses – De Niro and DiCaprio – finally united and along for the ride.
