Music, alcohol, drugs - their passions run riot. One of the seven, Brie Weissman awakens from a drug induced sleep. She is completely alone. Something is very wrong! Her mobile phone rings. A gruesome smiley face icon appears and a sinister voice delivers a chilling message: "The fate of your friends is in your hands Brie, there are only two rules, no parents and no authorities". Live video images then appear of her six friends, unconscious and incarcerated in wooden 'coffin like' boxes. Is this a prank or is there something more evil unfolding? The clock is ticking and it's up to Brie to solve the clues in a terrifying game of hide and seek with the lives of her friends in grave danger. It's a race against time as one by one the fate of Brie's friends begins to play out and the body count starts to mount.
