One night, Habib meets Shirin, Qasim's friend, in a notorious neighborhood and offers to marry her if she repents. Habib takes Shirin to Mashhad and gives his sister Maryam to Tahir. Qasim, who holds a grudge against Tahir, insults Maryam. The local baker, who witnesses the incident, remains silent, and Tahir marries Maryam to protect his reputation and that of his friend.
