In an attempt to survive, he and a few colleagues clumsily navigate their way through a maze of deadly encounters with infected, flesh hungry co-workers. As they try to escape the clutches of death, they unwittingly discover that the infecting agent was intentionally unleashed to cover up a controversial weapons program which was secretly being developed inside the building’s laboratory.
