CineCalidad. On a cold December night, a group of socialites, each with something to hide, are invited to the residence of an eccentric billionaire only to find themselves caught in a psychological game of cat and mouse with their host. But things take a turn for the worse when someone begins killing the guests one-by-one. As gruesome deaths lead to mounting paranoia, the rapidly dwindling party-goers must face not only a murderous psychopath, but also their own haunted pasts, if they are to survive the night.
