The Anniversary

Three couples. One weekend. Everything is about to change...

It's the Bank Holiday weekend and the Cunningham family are escaping to their holiday home by the sea, as they've done every summer for many years.

Except that now, parents Lily and Charlie are waiting for their divorce papers to come through -- and have their new partners in tow.

Their daughter Poll is there with her boyfriend and is determined to make known her feelings for Chloe, her father's new love. While her brother Thomas also has feelings for Chloe -- of a very different nature...

And amid all the drama, everyone has forgotten that this weekend also happens to be Lily and Charlie's wedding anniversary.

Will any of the couples survive the weekend intact?
