The 'Kick-Ass' and 'Carrie' actress has an out-of-body experience in the first look at the new Gayle Forman adaptation.

Chloe Grace Moretz is no stranger to kicking ass and burning down the prom. But for her next act, the young actress is attempting to bring you a new kind of heartbreak.

Moretz is the star of "If I Stay," based on the young adult novel written by Gayle Forman. It centers on Mia, a young cellist with nothing but boundless opportunities on the horizon. She's been accepted into Julliard. She's falling in love with a guitarist named Adam. Her torn feelings between her professional and personal future are the greatest conflicts in her life.

And then comes the crash.

Mia's world is turned upside down during a horrific car accident that kills her parents, and leaves Mia in a coma. She has an existential, out-of-body experience where she realizes she has a choice to make: stay alive and struggle through the extraordinarily difficult tragedy, or allow herself to pass on.

It's a powerful, emotional conflict that plays to great tragic effect in this first, exclusive look at the "If I Stay" trailer. In addition to Moretz, the film stars "The Killing" veteran Mireille Enos as Mia's mother, and relative newcomer Jamie Blackley as Mia's boyfriend, Adam.

"The readers are very serious about me and Adam, and they really need that palpable relationship, and for me, I just want to go in there and create that relationship with Jamie," Moretz told MTV News last October, ahead of production. "It's that young love, and you have to capture that feeling."

"If I Stay" hits theaters on August 22.
