A girl is found in the wreckage of a car crash. Severely injured and psychologically damaged, the girl cannot or will not tell the authorities who she is or where she comes from. Her carers call her "Len", after the name embroidered on the jumper she was wearing when she was found.
Secretive, intelligent, and abrasive, Len is moved to a children's shelter. Slowly, Len's repressed memories fight their way to the surface of her troubled mind. And an evil figure from her shadowy past comes looking for her.
