Gofar (Gofar Hilman) and Guntur (Guntur Triyoga) who work as radio broadcasters in Jakarta, always feel someone is watching every broadcast of their Midnight program. Guntur also always feels scared because there are sightings of casting demons. The radio station is a building with a production house office that often holds casting.

Trapped in an empty building, nine people are forced to play a lethal game. All their movements will be recorded, and only one player can survive.
