He reports to the local agricultural cooperative with the intention of putting his theories to increase milk production in the cows into practice. One is stubborn at first, but one turns like a leaf on a tree if one suspects that he may be the son of the agricultural commissioner Plánička. Blažena Škopková is given the task of spawning and spying on him and everything seems to be arranged. However, the jealousy of Blažena's boyfriend Venca was not counted on.
