Xavier Ireland is a radio DJ who by night listens to the hopes, fears and regrets of sleepless Londoners and by day keeps himself very much to himself - until he is brought into the light by a one-of-a-kind cleaning lady and forced to confront his own biggest regret. This is a tale of love, loss, Scrabble and six degrees of separation, asking big questions about life and death, strangers and friends, heartache and comfort, and whether the choices we don't make affect us just as powerfully as those we do.
