In post-Katrina New Orleans, father Ledoux, an Afro-American priest, tries to prevent the closure of the Saint-Augustin parish. Fervent Christians, his parishioners are convinced that prayer and music can save the church, a symbol of the collective memory of slavery, where emancipated Africans, slaves and whites gathered together to worship for the first time. Gradually however, they have to face the obvious: the lack of money cited by the archbishop, as a reason is merely a cover for his cupidity and deep-rooted racism. Determined to save their church, the congregation resolve to take more militant action.
