Mayang, a former business legend who now lives a simple life as a watermelon farmer, returns to the city to attend the wedding of his adopted son, Tedy. Tedy, who is about to marry Ratu, the daughter of a businessman, has lied to the Ratu family by saying that his parents are dead. When Mayang comes with food, Tedy asks him to leave. Even though he is angry, Mayang finally forgives Tedy. On the wedding day, Mayang came dressed in simple clothes and was humbled by the Queen's family, including Tedy himself. However, Mayang has secretly prepared big gifts, including the position of main director for Tedy. As a lesson, Mayang did not invite the Queen's family to her exclusive dinner. Tedy and his family, who tried to attend the event by cheating, were humiliated when Mayang's real identity was revealed. In the end, Mayang punished Tedy by disowning him and leaving him in poverty.
