The coup in the Solar System failed. The Munkэ Chingisэan boevik army—its Mentor—was discovered with the help of the special unit "Invisible" and destroyed, while he himself fled from Earth.
Captain Krass receives an order to immediately go in search of the Mentor, who is trying to create an unbeatable army of "star nomads" deep in outer space—and, upon returning with it, seize Earth. The Mentor and his followers serve the Luon race: great scientists from the center of the galaxy who created the military might of the Abrog empire, but started their own game.
Earth’s intelligence learns that a military mutiny has begun in the galaxy’s core—one that threatens to grow into a full-scale war for supreme power in the Abrog empire. Following their goal, the "Invisible" units go straight into the thick of it. But the Earthlings have no idea that they are holding the secret threads of intrigue for a global war in their own hands.
