A Muslim fighter is injured in a clash with security officers. His sister rescues him from the officers and he takes refuge in a house frequented by the son of a high-ranking SAVAK official, who is not a Muslim. The young man falls in love with the girl, but her father, a SAVAK officer, who is against their marriage, creates trouble for the fighter's siblings. As a result of the sibling clashes, the boy is influenced by the sibling's actions and converts to Islam and marries the girl. A short time later, he and the girl's brother are killed in a clash with security officers.
