Set in Bangalore, one of India's largest cities, this series comes from Gautam Singh's award-winning documentary of the same name.

Twelve-year-old Marappa had a brutal childhood. His father was an alcoholic who sexually abused him, and made him beg. His mother was burned to death while trying to avoid being raped.

Marappa's father died leaving behind a huge debt of 300,000 rupees ($4,700) - an amount Marappa's relatives expected him to pay back. So he and his younger sister Laxmi ran away from home and lived on the streets.

But a few years ago, Laxmi went missing. Marappa was picked up by Mioi Nakayama, a social activist, and brought to Bornfree - a hostel and special school for street kids where they're taught arts and crafts to help them deal with their traumatic childhoods.

The art helps, but Marappa cannot forget that his baby sister is somewhere out there. So he decides to search for her, and Mioi agrees to help.

But finding a little girl in a city of 4.3 million people is no small task, especially for a 12-year-old boy.

In India, 11 children go missing every hour. Many of them are abducted by their own relatives and held for ransom or turned into slaves - made to beg or work as labourers. Often they're also sexually exploited.

This five-part series follows Marappa on his quest to find his sister and rescue her from such a fate.
