The residents of Pepys Road, London - a banker and his shopaholic wife, an old woman dying of a brain tumour, a family of Pakistani shop owners, the young football star from Senegal and his minder - all receive an anonymous postcard one day with a simple message: We Want What You Have. Who is behind it? What do they want? As the mystery of the postcards deepens, the world around Pepys Road is turned upside down by the financial crash and all of its residents' lives change beyond recognition over the course of the next year.
