Couples form a committee that plans the birth and selects the healthiest parents. To prolong life, a city of clones is built, which are used for implantation. The government assures that the latter do not have their own consciousness - only what was written down to them when they were created. A girl sociologist goes to the island of clones to find out what is really happening there.
