His movies seem to be quite simple in premise. Take something quite mundane & then throw in something demonic. This is more of a “getting your own back” movie. Something that you would always like to do when you get fired. What you don’t expect is to be locked in when all of your ex co-workers go a touch psychotic and are trying to kill you, and each other.
Derek Cho is having a really bad day. After being unjustly fired from his job, he discovers that the law firm’s building is under quarantine for a mysterious and dangerous virus. Chaos erupts throughout the office as the victims of the disease begin acting out their wildest impulses. Joining forces with a former client who has a grudge of her own, Derek savagely fights tooth and nail to get to the executives on the top floor and settle the score once and for all.
