At the age of five, Saroo was lost on a train which took him thousands of kilometres across India, away from home and family. Saroo survived alone on the streets of Kolkata, before ultimately being adopted by Tasmanian couple, Sue and John Brierley. Twenty five years later, armed with only a handful of memories, his unwavering determination, and the revolutionary technology Google Earth, he set out to find his lost family and finally return to his first home.

Lion is based on Saroo’s autobiography A Long Walk Home and is in cinemas this Thursday (January 19).

Saroo and his adoptive mother Sue Brierley came into the 6PR studio to chat with Simon Beaumont.
