On the planet Munkaid, a grandiose new type of starship was built, the Pandora space factory, created for the purpose of detecting and extracting dangerous viruses from space. Pandora's Box was ready to open and release a new Perfect Evil into the world! Mutagenic bacteria have been concentrated in special cones that are ready to throw them out and attack the main planets of the system. The owners of Pandora will use the latest weapons in the galaxy and become its masters for many years. Who can resist the one who controls the “cosmic plague”? The events in the book show how viruses, so far unknown to science, carried by cosmic dust, can become a serious danger to humanity.
