Tock is a little boy -- grown to be a man -- got lost while his family was touring the London Clock Tower when he was six. He climbed all the way to the top, fell back on a few steps, hit his head, and now he can't remember who he is. Twenty years later, he meets someone who will change his whole world. But she doesn't stay long, she receives a job in America and tells him at the last minute. Will he let her go to America and leave him to a life of loneliness or will fight to keep her with him?
