The documentary film "There is no turning back" by Stéphane Kleeb tells the story of the Tibetan siblings Losang and Dechen Barshee, who came to Switzerland as refugee children in 1964. After a difficult childhood in various foster families, they return to Tibet with their mother 40 years later. This journey confronts them with the alienation from their mother and their changed homeland. The film addresses homelessness, uprooting and lost dreams.
