Godspeed.

Mehri and Keyvan spend their holidays in Bandar with their parents. Mehri falls in love with a young man named Hemet, and Keyvan falls in love with Hemet's sister (Zinet). Despite their parents' approval, the two couples decide to get married. Zeinet and Keyvan get married, and Hemet goes to Tehran to buy a wedding dress. But he loses his money and, since he has no intention of returning, he stays in Tehran. Zeinet is unloved by her family, and when she gives birth to her child (the child is black), Keyvan drives her away on the pretext of infidelity. The family doctor shelters Zeinet, and Mehri commits suicide in order to blame her parents, but a series of incidents and actions taken by the doctor resolve the problem and the two couples live a peaceful life.
