The experimental drug Nexus-5, created using nanotechnology, has incredible potential. The program is loaded into the person’s consciousness - and before us is another personality. He is as charming as Don Juan, and his reaction, strength and agility are not inferior to Bruce Lee himself. A sky-high level of intelligence, a fantastic memory, the possibility of telepathic communication with other lucky people who have access to the miracle drug. Each new version of the nexus gives new opportunities, and nexus-5 - a new form of existence in which the superman retains only an external resemblance to the previous shell - already poses a threat to society and is prohibited by law. Only six months have passed since the events described in "Nexus" . The scale and speed of the total upgrade of humanity is amazing, and the main developer of the nanodrug is faced with a dilemma: continue working on the nexus in order to further “improve” the human race or stop the dangerous game with consciousness, in which the winner may turn out to be a loser?
