Mr. Kartolo took his feverish son Agus to see the neighbor doctor Budi. However, when the doctor asked to see the patient, Mr. Kartolo mistakenly called in his brother Kardi instead of Agus. Kardi then proceeded to call all of his nephews into the examining room, confusing the doctor. The doctor angrily yelled at them, trying to find his actual patient Agus, while realizing he needs a trip to the mental hospital to deal with the crazy family.
