In everyone's life there is a still attractive but hated ex. For Addie, this is Dylan - the son of rich parents, an Oxford student, a poet with a beautiful body and the man who broke her heart. Four years ago they met in Provence, and it was the best summer of their lives. But two years later, Dylan made a mistake and let go of the only girl he had ever loved. On the eve of the wedding of a mutual friend, their paths cross again, or rather, collide: at the very beginning of their trip to Scotland, the car of Dylan and his friend Marcus crashes into the one where Addie is driving and her traveling companions. So the company is waiting for a joint trip in a “Mini Cooper” full of luggage, past grievances, disappointments, awkwardness and secrets. What will not survive first: the car or the fragile peace between the passengers?
