In 1985, when he was 16, Ugandan Okello Sam was kidnapped and forced to fight with one of his country's rebel factions. Years later, his brother was similarly abducted by the notorious Lord's Resistance Army led by Joseph Kony. Sam eventually escaped and built a new life as a musician and actor. He performed in The Last King of Scotland and now leads a 28-member dance group called Mizizi Ensemble.
To help at least some of the huge numbers of children orphaned by war or escaping from fighting in it, in 1998 Sam bought a 40-acre patch of land and built Hope North. It now houses an accredited secondary school, an international arts center, vocational training, and a working farm. The charity says that more than 1,500 vulnerable youths have lived there.
Check out these pictures for an intimate look at what happens at Hope North.
And tonight, check out TakePart Live's interview with Weeds star Hunter Parrish to find out why he got involved with the group.
