The Lighthouse is the story of two men on an island, and how isolation slowly challenges their sanity. Thomas (Willem Dafoe) is a tough and haughty man with huge experience with marine life. Ephraim (brilliant Robert Pattinson), which is much younger, has a secret that made him choose the isolation in the lighthouse. The extended time on the island becomes a test for those two broken men. They must face their demons with the company of severe weather and mythical creatures. The movie blurs the difference between imagination and reality, which makes it a true journey through human psyche.
