In 1967, a strange disease was prevalent in the mercenary barracks in the Motaba River Valley, Zaire, Africa, and people continued to die. The US military doctor took the infected blood sample and left by helicopter. In the evening, a plane flew in and dropped a fuel-air bomb, and the entire barracks were destroyed in an instant. Only the frightened white-faced monkey was screaming in the nearby woods.
The time is already in the 90s. Colonel Sam of the American Institute of Infectious Diseases received instructions from his superior, General Billy, to go to Africa with his colleague Major Thor to investigate a strange virus in Zaire. What they saw was very miserable and shocking. Fortunately, this virus does not spread through the air, so it is easy to control. Sam left after taking a sample of the virus. At the same time, an American young man named Jinbao captured a small white-faced monkey in the woods near the village where the disease occurred, and prepared to take it back to China for sale.
Sam named the virus he collected "Mutaba Sam Virus". But after making the report, Sam received a notice to stop the investigation. It turned out that the virus this time was very similar to the virus discovered in 1967, and the latter had already been used to make biological weapons. Unknowingly, Sam was assigned a new job.
At this time, Campbell had secretly brought the monkey he had caught in Zaire back to the town of Cedar Creek in San Francisco. Since the monkey did not meet the buyer's request, Jinbao had to find a forest and set it aside. But a mysterious disease quickly spread in Xiangbai Creek. After learning of this, Sam did not obey the orders of his superiors to go to the new work place, but drove to the town of Xiangbaixi with Sol. The army was urgently dispatched to blockade the town, and anyone who wanted to escape was killed. Billy shipped a batch of venom serum but to no avail. Sam understands that this batch of serum is actually an eradication potion for biological weapons. In order to keep the secrets of biological weapons, the government allowed the virus to wreak havoc in Africa. But now the virus spreading in Xiangbaixi Town has mutated, and the original serum has no effect. The only way is to find the original carrier of the virus, the little white-faced monkey. But at this time, Washington’s staff headquarters had already made a decision to drop a fuel-air bomb to destroy the entire town along with the virus. Sam and Saul want to find the monkey and make a new antiviral serum to prevent the tragedy from happening. But their actions have led to military pursuit. The staff even falsely claimed that he was a dangerous fugitive virus carrier and wanted them on TV.
Sam and Sol finally found the monkey. They broke into the TV station with guns and announced the truth of the incident. At the same time, Billy, who learned the news, was trying his best to delay so that Sam could create new antibodies. After intensive work, Sam finally produced a new anti-drug with satisfactory results. Sam finally rescued the people in the whole town with his hard struggle and strong will.
