The story begins as WikiLeaks founder Julian Assange (Benedict Cumberbatch) and his colleague Daniel Domscheit-Berg (Daniel Brühl) team up to become underground watchdogs of the privileged and powerful. On a shoestring, they create a platform that allows whistle-blowers to anonymously leak covert data, shining a light on the dark recesses of government secrets and corporate crimes. Soon, they are breaking more hard news than the world's most legendary media organizations combined. But when Assange and Berg gain access to the biggest trove of confidential intelligence documents in U.S. history, they battle each other and a defining question of our time: what are the costs of keeping secrets in a free society-and what are the costs of exposing them?

While in the hospital for a tomography of the brain of his autistic daughter Sarah, Ben becomes upset when there is a power failure. He decides to leave the hospital with Sarah, while the nurse Emily tries to convince him to leave Sarah for further treatment. They get the elevator with three other passengers, and suddenly the elevator stops; when the door opens, people has vanished from the hospital, the environment is creepy and they are chased by devilish monsters. They find that they are trapped in the hospital, and the creatures seem to be hunting Sarah.
