12 year-old Pavel, the clever though somewhat lazy and disobedient son of an assistant at a research institute steals a piece of artificial tissue from the laboratory of his mum’s superior, the lecturer Trčka. During a night-time storm the tissue transforms into a clone of the boy. As the disposition of the clone is determined by the momentary mood of the organism, a kindly Pavel II and an unruly Pavel III are created.
