What sort of mother would leave her all alone... a gripping and heart-wrenching domestic drama that won't let you go. Lily, who is almost three years old, wakes up alone at home with only her cuddly toy for company. She is afraid of the dark, can't use the phone, and has been told never to open the door to strangers. But why is Lily alone and why isn't there anyone who can help her? What about the lonely old woman in the flat below who wonders at the cries from the floor above? Or the grandmother who no longer sees Lily since her parents split up? All the while a young woman lies in a coma in hospital – no one knows her name or who she is, but in her silent dreams, a little girl is crying for her mummy... and for Lily, time is running out.
