The movie tells about the outbreak of a virulent bacteria in a secret military laboratory operating under the guise of a pesticide manufacturer. During routine work a sealed tube is broken, releasing the secret biological weapon. Where upon detecting the release of the agent, one of the plant's security officers activate "Protocol One," a procedure sealing all of the workers inside from the outside world and they are left to wait out the deadly effects. A local County Sheriff whose pregnant wife, the security officer, is trapped inside, and with the help of a past employee who is a known alcoholic, must fight through a government agency and the chemically affected workers to find his wife and put a stop to the spread of the lethal weapon. The former employee had started creating an antidote to the weapon, which the sheriff and his wife create and deploy.
