Deep space exploration continues. The crew of the spaceship "Daring" is ready to go to the boundaries of the Universe, beyond which lies the unknown and new discoveries. But first it is necessary to protect the Earth and the solar system from the attack of Kurt Schneider, who has subjugated the “murex” - an object of the inhabitants of the planet Nymph that has incredible power and weapons. Fate again puts Lieutenant Ivan Lomakin before a life choice: risk himself in the hope of winning or follow the beaten path, stay alive, but pay for it with his soul and conscience. The road to the borders of darkness begins.
