1862, a remote mountain inn in the French Hautes-Alpes.

Each winter, the owners entrust the place to two caretakers.

This year, Gaspard—an old hand who’s been coming for years—is joined by the young and inexperienced Ulrich…

Upon arrival, Ulrich meets Louise, the innkeepers’ daughter, and feels an intense attraction to her.

But when he finally decides to go to her, it’s too late: heavy snowfall has cut off all access to the valley.

Ulrich is devastated.

The next day, Gaspard sets off on a hunting trip and never returns.

Will the young man, haunted by his fears and fantasies, survive the terrifying loneliness?
