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 isn't there anyone who can help her? What about the lonely old woman in the flat upstairs who wonders at the cries from the floor below? 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...
