Detective Elin Warner, on leave from her job and grappling with past trauma, reluctantly accepts an invitation to her estranged brother Isaac's engagement celebration. The venue: Le Sommet, a newly renovated five-star hotel in the isolated Swiss Alps. Formerly a sinister sanatorium, the imposing structure, despite its minimalist luxury, radiates an unsettling atmosphere that immediately puts Elin on edge. As a ferocious storm descends, trapping all guests within the hotel's remote confines, Elin's instincts scream danger. Her unease spirals into dread when Isaac's fiancée, Laure, vanishes without a trace the following morning. Cut off from the outside world by the blizzard, Elin is forced to confront the escalating panic among the guests and the hotel's chilling history. With suspicion mounting and the body count potentially rising, Elin is thrust into a terrifying investigation where everyone is a suspect, and the dark secrets of Le Sommet threaten to consume them all. She must race against time to uncover the truth before the mountain claims another victim.
