The story revolves around Augustin Muganza, a Hutu who struggles to find closure after bearing witness to the killing of close to a million people in 100 days while becoming divided by politics and losing some of their own family. The plot intersperses between the genocide in 1994, and April 2004, when Augustin is invited by his brother, Honoré Butera, to visit him as he stands trial for his involvement in the genocide.
