Budi, an autistic person, and his family come to Jakarta to try their luck. He tries to keep his promise to buy new clothes for his children, Ratih and Iyan, if they are able to fast for a full month during Ramadan. Fate speaks another.

As Eid was approaching, Iyan suddenly fell down with dengue fever and had to be treated at a health foundation. Budi still believes he can keep his promise. Budi got a job as a construction worker tens of kilometers from his house. When he returned to the health foundation to pick up his wife and children and at the same time complete the payment.
