In 1967, during the Kisangani Mutinies a virus called Motaba, which causes a deadly fever, is discovered in the African jungle. To keep the virus a secret, U.S. Army officers Donald McClintock and William Ford destroy the camp where soldiers were infected. Twenty-eight years later, Colonel Sam Daniels, a USAMRIID virologist, is sent to investigate an outbreak in Zaire. He and his crew—Lieutenant Colonel Casey Schuler and new recruit Major Salt—gather information and return to the United States. Ford, now a brigadier general and Daniels' superior officer, dismisses the latter's fears that the virus will spread.
