Katie Williams is a kind, normal girl. She has gone through some difficult times and has a hard life trying to care for her sister Lauren who was in an accident 6 years ago and is now in a wheelchair, while her parents work 24/7.
She loves Lauren and so does their older brother Jason but they are getting fed up and need a break from running around from her.
When Lauren gets to make the wish of a lifetime everything changes and Katie's life is turned upside down, yet again.
