To protect Earth from a flux of asteroids, in 2033 on the Moon a complex of special facilities was built. An ordinary technician Yue Dugu missed the evacuation of personnel when part of the defense failed, and the asteroids unleashed a global catastrophe on Earth, and he witnessed the destruction of the planet. Now Dugu believes himself to be the last person in the Universe and does not know that remnants of civilization on the surviving equipment are watching him in real time, with no possibility of feedback. Additionally, at the lunar base a large red kangaroo-like creature has been discovered, very strong and dangerous.
