Bank Koperasi Tani dan Nelayan

After serving 10 years as punishment for carok (the practice of blood revenge with a sickle-shaped knife by the Madurese), Samsu helps his village fishermen’s co-op. Later, he resigns when he can’t get along with the investor, a beautiful rich widow, Lukitaningsih, who wants to gain personal profit from the co-op. As a result, he also quarrels with his lover, Pijah, and her father, Misral. Samsu then becomes a fisherman. Lukitaningsih tries to lure Samsu and the co-op to bull racing, which is one of Samsu’s skills. Seeing her efforts, Lukitaningsih’s driver, Dani, is envious and instigates Mahmud, against Samsu. Meanwhile, Misral and Pijah begin to understand Samsu so they change the co-op to the way that Samsu wants it to be, and they reconcile. Meanwhile, Mahmud loses the bull race and his carok challenge is answered with a friendly handshake instead.

Tabung realises that he must free his fellow villagers from the extortion by loan sharks, Jontro and Sadar. But Tabung, is a cripple, so he gets the help of the Farmer and Fisherman Cooperative Bank. He commutes to the city to handle the villager's credit, and is supported by his neighbour, a war widow. He expects Mardi's assistance, but Mardi is afraid to help for fear of losing his girlfriend, Narsih, who is actually Jontro's daughter. Finally, Tabung establishes the cooperative and the villagers gain the courage to fight off Jontro. Jontro now loses his livelihood so he begins to extort from Mardi, whose parents owe him money. Then Mardi comes to his senses. So does Jontro's right hand, Sadar. In the end, Sadar and Jontro have a face-off, and both are killed in the brawl.
