In If I Stay, an adaptation of the novel by Gayle Forman, Chloë Grace Moretz plays a talented cellist called Mia Hall, who is preparing for an audition at the Juilliard School. She has a handsome, thoughtful boyfriend (he’s even in a band) and a loving family. When you’re that high up, there’s a long way to fall.

Cue a devastating car accident that leaves Mia’s parents dead and herself detached from her unconscious body, wandering around the hospital as doctors work to save her life and reliving her short seventeen years of life. With her boyfriend Adam (Jamie Blackley) and her friends and remaining family by her side, Mia must decide whether to stay behind in her wrecked life or move on to whatever lies beyond.

Comparable to the upcoming adaptation of John Green’s The Fault in our Stars in its blend of serious subject matter and budding teenage romance, If I Stay looks set to be one of this summer’s merciless tearjerkers. MTV has just released the first trailer for If I Stay, and as A Great Big World’s “Say Something” plays over footage of Mia watching scenes from her very earliest infancy, you’d be forgiven for reaching for a box of tissues.

If I Stay was directed by documentary filmmaker R.J. Cutler from a screenplay by Shauna Cross, who also wrote both the novel and screenplay for Drew Barrymore’s roller derby drama Whip It. Moretz competed with other young stars Dakota Fanning and Emily Browning for the lead role, and the final cast list includes Joshua Leonard (The Blair Witch Project) as Mia’s father and Mireille Enos (World War Z) as her mother.

This trailer certainly seems to be playing up the romance between Mia and Adam, and if the movie does the same then this could be the perfect summer date movie – albeit a somewhat depressing one.

If I Stay is out in US theaters on August 22, 2014.
