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. How he ended up on the streets of Calcutta. And survived. How he then ended up in Tasmania, living the life of an upper-middle-class Aussie. And how, at thirty years old, with some dogged determination, a heap of good luck and the power of Google Earth, he found his way back home.

Lion is a triumphant true story of survival against all odds and a shining example of the extraordinary feats we can achieve when hope endures.
