Five couples are barricaded inside of an old Victorian home in an isolated vineyard. Lured there with the promise of a relaxing retreat, they quickly learn the organizer has ulterior motives. While ten "innocent" people have walked willingly into this retreat, not all of them will have the ability to walk out. One by one each of the guests are forced to describe which of the Seven Deadly sins they have committed. The leader of this charade wants them to pay for those sins with their life. Because this is a game for sinners. And sinners must die.
