Setelah kematian Paus yang tak terduga, Kardinal Lawrence ditugaskan untuk mengelola ritual rahasia kuno dalam pemilihan Paus baru. Terisolasi di Vatikan bersama para pemimpin paling berpengaruh dalam Gereja Katolik hingga proses tersebut selesai, Lawrence mendapati dirinya berada di tengah konspirasi yang dapat mengancam kehancuran Gereja.
CONCLAVE carries the weight of judgment—reminiscent of Pope Francis' bold question, "Who am I to judge?" both literally and figuratively. Edward Berger's film unravels like a claustrophobic thriller within the Sistine Chapel, where intrigue, politics, and faith collide—not just to determine the next successor, but to shape the future direction of the Church. It's beautiful, brave, and at times, as challenging as faith itself. Yet, Ralph Fiennes' god-like performance shepherds us through with a humbling sense of triumph.
