Having lost its former economic power and leadership in strategic offensive weapons, the United States began to slowly but inexorably lose its dominant position. An acute desire to stop the process, after futile attempts to break the Chinese economy and the military strengthening of Russia, pushes them to a desperate step - the use of biological weapons disguised as natural epidemics. The unsuccessful attack on China prompts a modification of the approach taken during the attack on Russia. The Foreign Intelligence Service becomes aware of the location of the laboratory where a new strategy is being developed. Through Western journalists, they make noise about environmental problems in this region and bring the matter to the point that the government of the host country is forced to request international scientific assistance. It is impossible to include an eminent specialist or military microbiologist in the group of Russian scientists going there without disclosing an interest in the laboratory. Therefore, we have to send a young but talented scientist - a woman.
