What if your friends became senseless killers? What would you do? How far would you go to protect yourself? To save your own life, could you kill a friend? Nine friends have reunited for a birthday party in the Scottish highlands, the drink flows, relationships are rekindled, and everyone relaxes for the perfect weekend. What could possibly go wrong? It starts to snow and soon the group is entirely cut off from the rest of the world. The wind whistles under the doors, the house creaks, as a vicious, uninvited guest joins the party. The spirit of Murray, an old Scot patriot, is unleashed and is intent on murdering all nine guests. One by one they start to die as the spirit moves through them, from body to body, from friend to friend. It's survival of the fittest as all are pitted against one another. Only one will survive.
