An old man sits in a room, with a single door and window, a bed, a desk and a chair. Each day he awakes with no memory, unsure of whether or not he is locked into the room. Attached to the few objects around him are one-word, hand-written, labels and on the desk is a series of vaguely familiar black-and-white photographs and four piles of paper. Then a middle-aged woman called Anna enters and talks of pills and treatment, but also of love and promises. Who is this Mr Blank, and what is his fate? What does Anna represent from his past - and will he have enough time to ever make sense of the clues that arise?
