All your dreams will come to life. So will all your nightmares. ― After narrowly surviving the car crash that killed his best friend, Andrew King is left to grapple with his loss and nurse a traumatic brain injury. With his injury comes a crippling sleep disorder, and sick of the restless nights and fatigued days, Andrew joins a clinical study to correct it as one of four subjects. The promise of returning to normalcy is lost as his dreams begin to take harrowing turns, prophetic in nature and vivid enough to be confused with waking life. Andrew bands with the other subjects, and they learn that the study has left them with the ability to live versions of the future in their dreams. Together they embark on a journey to find the forces behind their newfound abilities, only to quickly discover that some doors are best left unopened.
