When We Leave tells the story of a young German/Turkish mother's struggle for self-determination between two systems of values. It is a multi-layered story about honor, intolerance, and the unshakeable belief in a harmonious coexistence. The film stars Sibel Kekilli, Florian Lukas, Alwara Höfels, Nursel Köse, and Turkish actors Settar Tanrıöğen and Derya Alabora. It was produced by Independent Artists, a company founded by Aladag in 2005.
