Capital (2015)

The residents of an affluent street in London are busy getting on with their lives, when suddenly something very strange happens. Every house in the street has an identical, mysterious postcard pushed through their letterboxes that simply states "WE WANT WHAT YOU HAVE". At first, the residents of Pepys Road dismiss the notes as some sort of marketing campaign but gradually as events begin to escalate it becomes clear that there is something more to this strange occurrence than something as mundane as that.
