Holidays are about surviving the gaps between one meal and another.

For one long hot summer in Devon, three families are sharing one very big house in the country. The Herreras: made up of two tired parents, three grumbling children and one promiscuous dog; the Littles: he’s loaded (despite two divorces and five kids), she’s gorgeous, but maybe the equation for a truly happy marriage is a bit more complicated than that; and the Browns, who seem oddly jumpy around people, but especially each other.

By the pool, new friendships blossom; at the aga door, resentments begin to simmer. Secret crushes are formed and secret cigarettes cadged by the teens, as the adults loosen their inhibitions with litres of white wine and start to get perhaps a little too honest …

Mother hen to all, Evie Herreras has a life-changing announcement to make, one that could rock the foundations of her family. But will someone else beat her to it?
