Two families. Seven days. One house. Angela and her brother Richard avoided each other for nearly 20 years. Now, after the death of their mother, they are taking their families on holiday to a briefly rented house on the border with Wales. Four adults and four children. Bonfire gatherings, joint dinners, card games. But behind this peaceful facade, ghosts of the past begin to appear. Parents, lovers, friends, enemies - everyone turns out to be not at all who they seemed.
