Note: Filmed as Virus (1996).

Synopsis: When a truck carrying a lethal plague virus overturns in a creek within Yellowstone Park, all hell literally breaks loose. The plague, a particularly virulent form of hemorrhagic fever that causes its victims to explode in showers of blood, quickly infects all humans and animals who come in contact with the contaminated water. A team of contract killers is given orders to track down and terminate any humans who might be infected.
