Jack in the Box plot
Six college students, seeking fame and money, are invited to a new reality show. But they soon discover that they have been locked up and must fight for their lives in a deadly musical musical chair. The game is led by Junior, a deformed serial killer with a terrible past. He has frighteningly simple rules: you live when you sit, you die when you stand. Every ten minutes, the nursery rhyme Pop goes the weasel signals a new round and then the desperate battle between Junior's guests begins to get a seat and save their lives. The contestants are eliminated one by one until there is only one seat left… and the last player remains alive.
