A young girl happily begins a new relationship with a boy she'd been friends with at school. But as time goes on, she finds herself taken for granted, and soon she descends into an alternative reality as she starts to lose herself. Daydreams and nightmares, instead of pulling her away from what's real, show her the truth of what's happening, and what she's lost. Reconnecting with the child and her former self that she finds in the dream world that appears behind the mirror in her bedroom, she slowly learns how to put the shattered pieces of herself back together, and emerges into the sunlight among friends again.
