The Beach (2000)

Richard (DiCaprio) is a typical twenty-something American whose head is filled with an absurd amount of pop-culture and video game references. While travelling in Thailand in order to broaden his horizons and gain some real world experience, he meets Daffy (Carlyle), a crazy Englishman who gives Richard a mysterious map before committing suicide. Apparently the map leads to an idyllic island where the inhabitants live in a natural paradise. Intrigued, Richard convinces two French acquaintances, Francoise and Etienne (Ledoyen and Canet), to journey with him and see if Daffy was right. Upon reaching the island, Richard discovers that it does, in fact, appear to be the dream that Daffy had promised. They meet Sal (Swinton), a strong-willed woman and leader of the group. Sal has made a pact with the weapon-wielding drug dealers who control the island that her group can remain there provided no new bodies arrive. Richard has a brief tryst with Francoise, but she abandons him when she discovers that he has had another sexual encounter while gathering supplies from the mainland. And when two drugged-out Americans show up and crash the party, Richard's newfound Utopia is threatened once and for all.
