Heidi Ewing and Rachel Grady's "The Boys of Baraka" offers a perceptive look at the lives of four young males from inner-city Baltimore who are given the opportunity to attend Kenya's Baraka School, which challenges them academically and attempts to instill self-discipline. The documentary follows up with the youths the following school year, when, due to a civil war in Kenya, they return to Baltimore's public-school system.
