Four women

Annie has brought her three best friends and their families together for a long weekend away in a gorgeous seaside Airbnb. It should be idyllic – sun, sea, sand, cocktails and laughter.

One shocking secret

But below the surface, none of these friendships are quite what they seem. And Annie has a secret – and an earth-shattering favour to ask of one of her friends.

A life-changing decision

As the idyllic weekend turns sour – arguments, grudges and a boat trip that goes awry – Annie must make her devastating decision – and change everyone’s lives, forever.
