Co-directors Jeff Zimbalist and Matt Mochary's acclaimed documentary charts the growth of Rio de Janeiro's AfroReggae movement, a grassroots effort to combat the soul-crushing oppression of the city's most notorious slum. Led by former street thug Anderson Sa, the nonviolent program celebrates Afro-Brazilian culture, drawing on hip-hop music and dance to unite the impoverished neighborhood against the ubiquitous drug pushers and corrupt cops.
