Lizzie Kent wasn't supposed to babysit the night she was murdered. She was covering for her best friend, Nell. Nell has lived with the guilt ever since.

Eighteen years later, Nell returns to the area, desperate to escape a bad relationship after inheriting her aunt's rundown guesthouse. But her return isn't welcomed by everyone - in particular Sam Kent, who blames Nell for his sister's death. And after a few unsettling incidents, it becomes apparent that someone is trying to scare her.

Is Sam responsible or has Nell's abusive ex-boyfriend managed to track her down? Or is someone else, with a more sinister agenda, responsible?
