Jaka Swara witnesses the slaughter of his parents by John Da Costa’s gang, a Portuguese who still controls a remote area. Jaka Swara painstakingly learns martial arts to seek revenge. When Fatma, is held captive by Da Costa, it spurs Jaka into action. Rhoma Irama’s rôle as Jaka is somewhat different from his norm due to the nature of the action film. He sings five songs for the romantic scenes.
Even though he is not a "left wing" student, Nurhadi, nicknamed Hadi, insists on becoming a volunteer in the fight against Malaysia. Wati, his lover, tries to stop him, but fails. She pretends to be pregnant so that Hadi marries her. But Hadi still goes to Malaysia. Hadi’s group is detected by a Malaysian patrol, when they are about to land in Malaysia, which leads to a firefight. Everyone dies except Hadi, who is found unconscious by Latifah at the beach. Hadi is taken care of by Latifah and his father, Somad. He claims that he is a fisherman who has been stranded and is named Mohamad Noor. The confrontation between Indonesia and Malaysia then ends. Wati still believes that her husband is alive and goes to Malaysia to find him. She finds Hadi already married to a pregnant Latifah. Wati goes home in disappointment.
