About the title
Due to global warming, a project for the survival of humanity was launched in 2063. A group of children was grown in test tubes from the biomaterial of specially selected donors. They never left the walls of the laboratory — they lived and were educated there under constant supervision, so as not to get used to sunlight and open spaces. While still very young, they set off on a journey to a distant planet suitable for life, but at best only their grandchildren will reach it. Soon, friends Zac and Christopher discover that the vitamin drink the whole crew — except for the adult accompanying them — takes every day contains a substance that makes them calm and obedient.
