What do you do when the wedding of your dreams turns into a nightmare?

When Lizzie calls off her wedding in the south of France only a week before the big day, not even her closest friends know why. But since the chateau is already paid for, they figure it's the perfect place to take Lizzie's her mind off her suddenly single state.

But when the group arrives, the wedding is waiting for them - food, flowers, and all.

The next day, Lizzie wakes to find her friends have drunkenly revelled in the wedding-that-wasn't - but not all their antics were benign. Someone is set on tormenting Lizzie, and she can't think who.

The more the friends try to piece together exactly what happened that night, the more secrets start to come out . . .
