The story of Zdeněk Troška's new comedy, which was inspired by countless stone jokes, takes us to a peaceful South Bohemian town. A whole range of typically Czech characters and prototype families live here with their unchanging rhythm. For example, the Nováks. Pepa's father is a captain of the city police, his wife Vilma is a teacher, his daughter Julia is studying health, and nine-year-old Pepíček comments in an unspeakable way on everything that is happening around. The boy literally starts to have eyes on top of his head when a noble couple arrives in Kameňákov from England, to whom the local castle was returned as part of the restitution. Nothing is hidden in a small town, and soon everyone knows that the lord has come here to look for his father's treasure. Such news will bring the whole of Kameňákov to its feet and literally keep three local mafia members, the rich Kohn, the handsome chief of police and the experienced criminal, awake. And then things start to happen...

Kameňák 2, inspired again by well-known and less well-known stone jokes (director Zdeněk Tročko received an incredible sixty thousand of them from the audience!) directly follows the first part, which ends with the gushing of a blue erectile spring from the rock at the Kameňákov castle. The miraculous effect of the blue spring on potency causes an unprecedented uproar in the town, and even old Kropáčková experiences its beneficial power. However, as suddenly as the spring appeared, it also disappeared. But did it really disappear? And where? The insidious granny Kropáčková knows this best, who in the second part becomes a terror to the young men in the town. The disappearance of the blue spring of a lucrative business has not let even the local mafia sleep. All traces lead unmistakably to the Kropáčková house in the manor house...
