A fifteen-year-old boy wakes to find himself locked in a white cube-shaped room. No windows, no doors, total silence. He has no memories, no clue how he got there - and no idea who he is. As the boy uncovers snippets of his story - an attempted abduction, a critical injury, a murder - it becomes clearer. But when some of the pieces don't fit, how can he tell what's real and what's not? Who can he trust? And who is he really?
