A group of friends decide to celebrate their high school graduation at a lake house in the woods. One of the classmates recommends that they play the old-fashioned game of ‘Dead Body.’ In the game, one player is “the body,” one player is “the killer” and all the other players try to figure out 'whodunit'.

The bodies begin piling up and, in an Agatha Christie 'And Then There Were None' style mystery, the survivors are forced to figure out who the killer is amongst them – before there is no one left standing.
