An illiterate child from a small town in India falls asleep on a train and ends up lost in Calcutta, unable to find his way back home. Twenty-five years later, while living with his adoptive family in Australia, he locates his lost hometown using memories and Google Earth:
This was it, the name of the station where he was separated from his brother that day, a couple hours from his home. Saroo scrolled up the train track looking for the next station. He flew over trees and rooftops, buildings and fields, until he came to the next depot, and his eyes fell on a river beside it—a river that flowed over a dam like a waterfall.
Saroo felt dizzy, but he wasn’t finished yet. He needed to prove to himself that this was really it, that he had found his home. So, he put himself back into the body of the barefoot five-year-old boy under the waterfall: ‘I said to myself, Well, if you think this is the place, then I want you to prove to yourself that you can make your way back from where the dam is to the city center.’
Saroo moved his cursor over the streets on-screen: a left here, a right there, until he arrived at the heart of the town—and the satellite image of a fountain, the same fountain where he had scarred his leg climbing over the fence 25 years before.
