The cliff house (engelsk)

Jen's hen party is going to be out of control. She's rented a luxury getaway on its own private island. The helicopter won't be back for 72 hours. They are alone, or so they think. It's a combustible cocktail, one that takes little time to ignite, and in the midst of the drunken chaos, one of them disappears. Then a message tells them that, unless someone confesses her terrible secret to the others, their missing friend will be killed. Problem is, everyone has a secret. And nobody wants to tell.
