During spring break, Emily and Jessica, twin sisters traveled to the Grand Canyon. But then while taking a selfie on the edge of a cliff, Jessica suddenly vanished. Emily was later handcuffed and jailed without bail. Encouraged by her parents, lawyers and her psychiatrist to plead insanity, she complies and is found guilty. Unable to convince anyone that she’s innocent and having nothing better to do, Emily journals her story.
While in solitary confinement her mind begins to unravel and forgotten details form a new, unexplainable reality. Emily begins to doubt everything she thought she knew. Was everyone right? Did she push her beloved twin sister to her death, or was it a selfie gone horribly wrong?
