An Australian World War I veteran (Michael Fassbender) takes a job as a lighthouse keeper on an isolated island. He meets his future wife (Alicia Vikander) at the nearest coastal town, and the two begin their new life alone at the lighthouse. Once settled, a lifeboat washes ashore with a newborn inside, and the couple raise the infant as their own. Rachel Weisz co-stars in this adaptation of M.L. Stedman's novel, which was written and directed by Derek Cianfrance (BLUE VALENTINE, THE PLACE BEYOND THE PINES).
