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.
