In a remote monastery in the mountains of Algeria, a group of French Trappist monks live in harmony with their Muslim neighbors. The monks lead a life of simplicity, prayer, and service, providing medical care to the local community. As Islamic fundamentalist violence starts spreading across the region in the mid-1990s, tensions rise. The brotherhood faces increasing threats from a radical group, sparking internal debates about whether to stay and continue their mission or to abandon the monastery for their safety. The monks, led by Brother Christian, confront their faith and commitment, as each monk must reconcile his devotion to God with the very real danger they face.

As the violence escalates and external pressures mount, local authorities and the French government urge the brothers to leave for their safety. Despite these growing dangers, many of the monks insist on staying, rooted in their commitment to support and stand in solidarity with their Muslim neighbors facing the same threats. They dedicate themselves to their monastery's mission of peace and coexistence, becoming symbols of courage and conviction. Their deep faith and moral choices become a central focus, exploring themes of sacrifice, friendship, and communal ties amidst the increasing dangers surrounding them. The tranquility of their monastic life stands in stark contrast to the external chaos, leading to a poignant narrative that delves into the essence of faith and humanity.
