"Karate-do" translated from Japanese means "Way of the Empty Hand." Arthur Belov followed it from childhood and by the time he was twenty he had achieved a lot. But, finding himself on the verge of life and death after the injury, he is forced to start the hike again, this time in virtual reality. Much here is familiar to him, some is new. But he has no idea where exactly he is going... or where he is being taken.
