When Milla is invited to a reunion in the French Alps resort that saw the peak of her snowboarding career, she drops everything to go. While she would rather forget the events of that winter, the invitation comes from Curtis, the one person she can’t seem to let go. The five friends haven’t seen each other for ten years, since the disappearance of the beautiful and enigmatic Saskia.
But when an icebreaker game turns menacing, they realise they don’t know who has really gathered them there and how far they will go to find the truth. In a deserted lodge high up a mountain, the secrets of the past are about to come to light.
