When Flora, James and their two teenage daughters are offered the holiday of a lifetime in a chateau in the south of France in return for one simple good deed, they jump at the chance. They exchange the confines of Clapham, the weight of the mortgage and anxieties over their future for a blissful break. But Flora didn't anticipate a mysterious guest and a whole heap of family baggage coming too. With James developing a schoolboy crush on a famous singer and Flora distracted by ghosts from her past, their dream holiday suddenly takes some very unexpected turns.
