九名高中生去木屋慶祝畢業，他們玩起了“死屍”遊戲，隨著同伴一個接一個地死去，原來凶手早已埋伏其間……Nine high school kids celebrate graduation at a secluded home in the wilderness. They fight, philander, and feel nostalgic as they embark on a life away from home, in college. Once the party dies down they play a game: Dead Body. But when one party-goer takes the game too far, actually murdering the other guests one by one, it's up to the group to set aside their tensions, and ferret out the murderer before it's too late.
