Ismet Ulam Raja is a wealthy businessman with three sons, Abdul Wahab, Abdul Wahib and Abdul Wahub. Abdul Wahab and Abdul Wahib are selfish and money-minded, running their individual businesses to success. Abdul Wahub, on the other hand, enjoys a simple life and owns a small music shop. When Ismet Ulam Raja has a heart attack on his birthday, Abdul Wahab and Abdul Wahib start plotting out how much wealth they are set to gain when their father dies. Abdul Wahub is appalled at their behaviour and tries to get their father to go to the hospital, although Ismet Ulam Raja is strongly against hospitals. Their father dies at home, and the two elder brothers immediately distribute their late father's vast wealth among the two of them while Abdul Wahub only inherits their father's house. Although Abdul Wahub is upset at this injustice, he accepts it as he is the youngest brother, and returns to his simple music business.
