Well-known travel blogger Sang Limin went to the "Wangxue B&B" in the mountains to take pictures of the beautiful snow scenery. However, a sudden blizzard trapped her and four other guests with different identities here, weaving an airtight web of despair. The owner of the B&B disappeared mysteriously, all communications and transportation were cut off, and a strange note that read "Tonight, someone will 'stay' instead of the owner" kicked off the bloody festival. The sin committed ten years ago, the revenge ten years later. When the past and present are intertwined, and hunters and prey interchange, in this snowy mountain cage, everyone may be the judge or the next sacrifice. What Sang Limin's lens records this time is no longer the scenery, but the abyss-like human heart.
