Le Sommet, half-hidden in the forest and overshadowed by the daunting peaks of the Swiss Alps, has always been a sinister place. Once an abandoned sanatorium long haunted by unsettling rumors, it has now been transformed into a luxury hotel. And it is the last place Elin Warner wants to be. But she took time off from her job as a detective to celebrate her brother Isaac's engagement to his girlfriend Laura here. Upon arriving in the midst of a terrifying storm, Elin immediately feels uneasy – the hotel disturbs her for no apparent reason. And when she discovers the next morning that Laura has vanished, Elin must trust her instincts and believe she can find her. The storm cuts off all access routes, and the longer Laura remains missing, the more the other guests begin to panic. Elin is under pressure to find Laura, but no one has noticed that another woman has gone missing. The only one who could have warned the others about the great danger they all face...
