HBO is debuting a documentary tonight about an orphan in India who ran 48 marathons by the time he was four years old.

The story of Budhia Singh circulated across the globe six years ago, but this documentary, filmed between 2005 and 2010, concentrates on the exploitation that took place after the initial publicity. What started as a heartwarming rags-to-riches story unfortunately became a tale greed, corruption, and broken dreams.

This documentary is the first of four about contemporary India debuting on HBO and HBO2 this month. The others are "The Bengali Detective" (Nov. 16, HBO2); "The Sound of Mumbai" (Nov. 23, HBO2); and "Pink Saris" (Nov. 30 on HBO2).

"Marathon Boy" airs on HBO tonight at 8 p.m.
