Tide: One night. On the deserted ski slopes, the nocturnal outing of the snow-grooming machines is being prepared. Twenty-five-year-old Antoine meets up with his team.

Immobilized in the night, Antoine begins a journey in the interval where the myths of a mountain, both feared and venerated, are embodied.
