In a tale that's almost too Hollywood to believe, then 5-year-old Saroo reportedly took a break from searching for change with his brother in Berhanpur, India, and hopped onto a stationary train where he fell asleep. Hours later, he woke up in Calcutta, alone and more than 900 miles away from home. He was taken to an orphanage and adopted by an Australian family.

A few years ago, Saroo used Google Earth's "ruler" feature to take a stab at figuring out how far he had traveled on that fateful day. After hours upon hours of scouring, he spotted a neighborhood that looked right.

Confident -- or at least as confident as he could be -- he made the trek home in 2012, talked to locals, and eventually found his mother, brother and sister.
