'If I Stay' prologue: 'Everyone is waiting on me'

“How am I supposed to decide this?” That’s the question that torments young Mia (Chloe Grace Moretz) through the entirety of If I Stay, the upcoming big-screen adaptation of Gayle Forman’s YA hit.

If I Stay follows Mia, a 17-year-old cellist who finds herself in a coma after a car accident that killed the rest of her family. The story then takes the audience through Mia’s memories and experiences as she tries to make the decision to either wake up or to die.

In a new preview video for the film, we get an in-depth look at Mia’s decision and some of the key memories that help her make it. Let’s just say that if the book made you cry, you might want to have a tissue nearby for this sneak-peek as well. After all, Moretz did tell EW that her goal with this film was to make the audience feel. “You want to watch something that actually means something and makes you feel and makes you want to be involved,” Moretz said. “That’s what I wanted to make and that’s what I strive to make.”
