Demi Lovato has a theory. And, it's that, what if there are multiple souls in your body, but you are the most powerful one so you control the body, and the voices in your head are actually the weaker souls talking to you? What if schizophrenic people just don't have an assertive soul so all of the souls are fighting to take over?
Adopting a schizophrenic twelve year old girl, Danielle, is Demi's opportunity to prove her point. But Danielle's days are numbered, due to a rare lung condition brought on by the excessive number of souls, and, so, with having to find out a cure for Dani's problem with her souls, as they begin to damage her system, Demi is having an extremely tough time.
However, despite the neverending, building load of trouble that each scar on Danielle's body -be it from self harm or surgeries- brings both Demi and Danielle, Demi never gives up, as she strives to teach Danielle the fault, in her scars.
