Algeria, 1954. Two very different men thrown together by a world in turmoil are forced to flee across the Atlas mountains. Daru, the reclusive teacher, has to escort Mohamed, a villager accused of murder.

This is a story about a fraternity that goes beyond cleavages and prejudices. A quiet and brave rebellion against nonsense of violence. Charlie, Niger... That's so cruelly acute to current events. No doubt this story, that takes place in Algeria in 1954, could have been transposed in 2015 or later.

The film is beautiful, it takes its time without being never boring. Action and contemplation are wonderfully balanced.

The relationship between two men, both excluded from their communities, "étrangers" (foreigners) in more than a way, is moving. Each of us is an Arab or a paria for someone else.

Reda Kateb, Viggo Mortensen and the Atlas are glowing, simply fascinating.
