The film is about a slightly crazy botany professor Ducánek, who is so busy with his scientific experiments that he has completely forgotten that he is married. Neither his housekeeper Veronika nor his friend Potužník knew about the existence of his capricious wife, the operetta diva Lucy. However, when his wife returns home after seven years in remorse, Ducánek takes a complicated action to elegantly get rid of his wife...
