Members of the secret lodge of the "Eternals" have not only power and wealth, but also the ability to change bodies like gloves. Most of them, having exchanged the second hundred, look no older than thirty. The meaning of their life is eternal youth, in the name of which, people are bred like cattle, which is expendable material for illegal nursery laboratories. The founder of the box, languishing from boredom, starts a game where people become puppets, and their lives become bets.
