Dentist Dr. Matys employs two laboratory assistants, brothers Alois and Benjamin Zoubkova. They also serve as occasional nannies, because the young doctor is living with his widowed stepfather, former forest manager Václav Bezdětek, and his four small children. The brothers would like to marry their beloved boss, but they know that they must first find a new wife for Bezdětek. All the men are irritated by the radio feminist lectures of a certain Marta Kočová, who preaches against men who serve women and even give birth to children "on demand"...
