In the near-future city of New Corinth, a powerful and enigmatic religious movement known as The Chosen beckons the lost and searching. "The Faithful" follows three strangers whose lives violently intersect: a disillusioned former journalist, played by John Boyega, who infiltrates the group seeking a story; a grieving widow, portrayed by Naomie Harris, desperately clinging to the community's promise of solace; and the magnetic, yet inscrutable leader, brought to life by Ruth Negga, who offers divine connection at a mysterious cost. This atmospheric drama delves into the shadows of belief, exploring the fragile line between devotion and manipulation, and the profound human need to belong. As hidden agendas surface and the movement's true nature begins to flicker into view, each character must confront what they are willing to sacrifice in the name of faith, forcing them to question everything they hold sacred.
