Toby Jones stars in this three-part BBC adaptation of John Lanchester's novel. The drama centres around the residents of the fictional Pepys Road in South London, where houses cost a small fortune. Occupiers of the street vary from those who have lived there since before the London property boom, including elderly widow Petunia Howe (Gemma Jones), to the recently moved in wealthier residents, including banker Roger Hunt (Jones). After all of the street's residents receive mysterious postcards bearing the message 'We want what you have', the interweaving connections between them begin to unravel.
