In the smoky, maritime world of early 20th century Europe, a seasoned sea captain makes a startling wager with a friend, betting half his fortune that he can accurately predict the infidelity of his future wife. This is the provocative premise of Ildiko Enyedi's sumptuous and enigmatic drama, which charts the obsessive love and corrosive jealousy of Captain Jakob Störr, played with brooding intensity by Louis Garrel. He marries the captivating and fiercely independent Lizzy, brought to life by Lea Seydoux, a woman whose mysterious inner world becomes the central mystery of his life. As Jakob’s voyage keeps him at sea, his mind remains anchored to the shore, consumed by visions of Lizzy’s possible affairs, particularly with a charming writer, portrayed by Gijs Naber. The film weaves a lush, atmospheric tale of trust, possession, and the stories we tell ourselves about love, exploring whether a relationship can survive when it is built upon a foundation of doubt.
