As a five-year old in India, I got lost on a train. Twenty-five years later, I crossed the world to find my way back home. Five-year-old Saroo lived in a poor village in India, in a one-room hut with his mother and three siblings... until the day he boarded a train alone and got lost. For twenty-five years. This is the story of what happened to Saroo in those twenty-five years.
