Far off the Breton coast on Île de Sein stands Ar Men ("the Rock"), a lighthouse that defies storms and waves, built in one of the most inhospitable places in France. The men who serve there in solitude refer to it as "the hell of hells," as its isolated location can sometimes mean weeks without contact with the mainland – and no evacuation in case of emergency. This is the story of Germain, who left life on land behind in the 1960s to overcome the wounds his soul carried. At Ar Men, he found his place. Following "A Spring in Chernobyl" and "White as the Moon," Emmanuel Lepage invites us once again on one of his extraordinary journeys with "Ar Men." "Ar Men" is a visually stunning documentary about one of the most inhospitable places on Earth and the men who live there to ensure safe passage for ships.
