Warning Sign is a 1985 science fiction-horror film directed by Hal Barwood and starring Sam Waterston, Kathleen Quinlan, Yaphet Kotto, and Jeffrey DeMunn.


In a secret military laboratory operating under the guise of a pesticide manufacturer, there is an outbreak of a virulent bacteria. 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.



Parts of the film were shot in Payson, Utah.[1]
