When the Hutu nationalists raised arms against their Tutsi countrymen in the African nation of Rwanda in April of 1994, the violent uprising marked the beginning of one of the darkest times in African history. Over the course of the next 100 days, brother would turn against brother, tearing families apart and resulting in the death of almost 800,000 people. Based on actual events that occurred during the uprising, Raoul Peck's affecting war drama tells the tale of two such brothers, whose differing loyalties found them on opposing sides of the conflict, and whose lives would never be the same following this tragic turn of events.
