On New year's Eve, Wade (Mark Wilson Mark Wilson), Robert (Pascal Langdale Pascoe Langdell), Nicole (Julia Ballard Julia Bellard) and other five strangers receive mysterious invitations to a party on the 27th floor of a building. To their surprise, however, the party room was decorated as a children's party, and everyone had their seats: pigs, losers, two-faced people, heartless and lover boys. Is it a prank? Or some kind of main party? Just when they were confused, the danger hit, and a party turned into a ruthless hunting game.
