When the parking area is taken over by the local government, Rio loses his livelihood. Mursali then helps him by offering his taxi for driving at night. Again he has to use his fists on this new job, but when he meets Lia, she advises Rio to become a boxer. So he goes to Oom Eddy’s boxing gym and his career takes off. But Lia distracts him from his training and his fights. He also forgets about his girlfriend in the village, Sinta (Ayu Azhari). His losing streak begins and then Lia dies during an abortion. So Rio goes back to his village. Oom Eddy and Rio’s friends try to lift his spirit up again. Then Rio returns to the boxing ring, and is victorious once more.
