Seven adventurous partygoers find themselves trapped in a sadistic game of death after accepting an invitation to a mysterious party. It's New Year's Eve, and a group of revelers are living it up on the roof of an abandoned skyscraper when five of the partiers receive an intriguing text message. According to the sender, there's an exclusive VIP party happening on the twenty seventh floor, and they're all invited. Once on the floor, however, the five guests and two party crashers quickly realize that they have fallen into a trap. The only way off of this floor is to follow a series of morbid clues left by a murderous psychopath. But who conceived these deadly games, and why have they targeted this specific group? As the contestants begin to die a series of spectacularly staged deaths, each precious clue becomes a genuine matter of life and death.
