It’s the wedding of the year – for all the wrong reasons…

I vow to make you pay for what you did.

Twelve years ago, school friends Sofia, Ellie and Rose made a vow. They promised never to talk about that fateful night. Never to tell anyone what they did.

Since then, they’ve all followed very different paths but as they come together to celebrate Ellie’s destination wedding it promises to be a weekend to remember…

It is meant to be the event of the season, but as things start to go wrong, they suspect someone is trying to punish them.

But if the women took a vow of silence, how can anyone know? And what lengths will they be willing to go to, to get their revenge?
