Saroo was only five years old when he got lost. He was travelling with his older brother, working as a sweeper on India's trains. "It was late at night. We got off the train, and I was so tired that I just took a seat at a train station, and I ended up falling asleep." That fateful nap would determine the rest of his life. "I thought my brother would come back and wake me up but when I awoke he was nowhere to be seen. I saw a train in front of me and thought he must be on that train. So I decided to get on it and hoped that I would meet my brother." Saroo did not meet his brother on the train. Instead, he fell asleep and had a shock when he woke up 14 hours later.

I didn't know where I was. I just started to look for people and ask them questions." Soon he was sleeping rough. "It was a very scary place to be. I don't think any mother or father would like to have their five year old wandering alone in the slums and trains stations of Calcutta." The little boy learned to fend for himself. He became a beggar, one of the many children begging on the streets of the city. "I had to be quite careful. You could not trust anyone." Once he was approached by a man who promised him food and shelter and a way back home. But Saroo was suspicious. "Ultimately I think he was going to do something not nice to me, so I ran away." But in the end, he did get off the streets. He was taken in by an orphanage, which put him up for adoption. He was adopted by the Brierleys, a couple from Tasmania. "I accepted that I was lost and that I could not find my way back home, so I thought it was great that I was going to Australia." Saroo settled down well in his new home. But as he got older the desire to find his birth family became increasingly strong. The problem was that as an illiterate five-year-old he had not known the name of the town he had come from. All he had to go on were his vivid memories. So he began using Google Earth to search for where he might have been born. "It was just like being Superman. You are able to go over and take a photo mentally and ask, 'Does this match?' And when you say, 'No', you keep on going and going and going."
