Nine strangers agree to spend one night inside an abandoned research facility for easy money. No danger. No drugs. Just a simple memory study in a building that's been closed for decades.
But the building hasn't forgotten what happened there.
One by one, the participants begin to die-each death tied to a numbered room and a patient who was erased during illegal personality-transfer experiments. As the survivors dig deeper, they uncover a horrifying truth: some of the memories inside their heads don't belong to them.
And the ghosts want them back.
To make it out alive, the remaining participants must uncover the secret behind the facility and decide what they're willing to sacrifice. Because in a place built to steal lives, survival might mean giving up who you are.
