While investigating the scene of a mass murder at Beacon Mental Hospital, Krimson City Police Detective Sergeant Sebastian Castellanos, his partner Joseph Oda, and Junior Detective Juli Kidman find themselves suddenly thrown into an unreal world, after hearing a high-pitched noise. Shortly after this occurs, Sebastian is separated from his partners and is forced to flee from a monstrous man wielding a chainsaw. Upon reuniting with his colleagues, they attempt to escape via ambulance while Krimson City is destroyed by a massive earthquake, eventually causing them to crash.
