Father Viktor, highly capable and successful in his profession, and his son Petr, an equally successful and promising student, suddenly find themselves in an unexpected situation – after the death of their wife and mother, these two exemplary models of the perfect man and student must deal with such a mundane matter as taking care of the household. As capable, intelligent, and successful men, they naturally see no problem with this. Their experienced neighbor Lupínek, a distinguished grandfather with four grandchildren to look after, warns them in vain and offers his help. Male vanity and pride are stronger. As a result, they gradually find themselves in a whirlwind of embarrassments, problems, and disasters that gradually erode their self-confidence and destroy their firm belief in their own perfection. Fortunately, Uncle Artur comes to the rescue.
