Madura Island
Muhammad Arief (Sayef Muhammad Billah), the son of poor family in Sumenep, Madura Island, greatly enjoys science, especially physics. His father, Muslat (Lukman Sardi), is a former salt farmer who became a driver after an economic downturn. His mother, Salmah (Helmalia Putri), has gone abroad in search of work; the family have not heard from her, and Arief misses her. Although it is difficult due to his economic situation, Arief studies physics diligently.
