Samboja, a thug who controls an area, catches Ceking and his friends who are trying to rape two girls, Dyah Setiowati and Marlina. Samboja tries to help and is stabbed. Samboja is thought to be the rapist and is arrested. One of the victims, Dyah Setiowati, defends him to the police and he is released. But this incident makes him an enemy of the drug syndicate, who the rapist Ceking works for. Although his friend, Leo, who also works for the syndicate, defends him, the drug boss orders his men to kill Samboja. Dyah, the daughter of a cultural attaché, sympathises with him, especially when she finds out that he visits the daughter of Astri, the prostitute, in the orphanage.
