Ashley is a young single mum raising her daughter, Eden, and working hard to do the very best job she can – until one night she can't find a babysitter and makes the decision to leave Eden home alone for a couple of hours, asleep inside a wardrobe. It is an action that begins a terrible downward spiral for both of them.

When Eden arrives at experienced foster carer Louise Allen's home, she has entered the care system because her mother is in prison. Eden is five years old and will not speak to any human. She begins exhibiting some other disturbing behaviours alongside the mutism, too, including torturing the family pets she loves. This eventually leads Louise to discover the pain and tragic reality behind Eden's Story.
