It's London, the week before Christmas 2007. Over seven wintry days, we follow the lives of seven characters across the city, from a hedge fund manager to a Tube train driver. Above the complex patterns of modern urban life, the writing on the wall appears in letters ten feet high, but the characters refuse to see it. As the gripping climax looms, they are forced, one by one, to awake from their blinkered present to confront the true nature of the world they inhabit.
