After being found living on the streets as a child, and with no memory of a life or family before that time, all Tom has ever wanted is a happy, healthy family of his own. Now even such a simple dream feels as though it is slipping away. But, one night on the London Underground changes everything. When the train he's on comes to a halt in the dark, Tom finds himself alone and frightened.
