A group of Catholic monks reside in the monastery of Tibhirine, where they live in harmony with the largely muslim population of Algeria. When a bloody conflict between Algeria's army and Muslim Jihadi insurgents disrupts the peace, they are forced to consider fleeing the monastery and deserting the villagers they have ministered to. In the face of deadly violence the monks wrestle with their faith and their convictions, eventually deciding to stay and help their neighbours keep the army and the insurgents at bay.
