January 1980. Joshua Oberon woke up in the Avalanche Hotel in the Swiss Alps. He has lost his memory, but quickly discovers that he is a security guard and has been tasked with investigating the disappearance of an eighteen-year-old girl, Katherine. However, Joshua has a strange feeling that something is wrong in the environment. An obsessive voice in your head warns you of danger. A silent bartender asks Joshua to follow him into the mountains on important business, even as a snowstorm begins. Joshua is so cold that he loses consciousness... and only comes to his senses in the hospital room. We are not in 1980, but in 2018. Joshua is not a security guard, he is a policeman, and the Avalanche Hotel has been closed for a long time. Meanwhile, a nearly frozen girl is found in the snow, and a photo of the missing Katherine is found in her pocket. What happened in that hotel many years ago? What secrets does the stranger hide? And will Joshua be able to understand all these inexplicable events?
