In the middle of the night, Mehtab's grandfather's condition worsens and Vahid goes to the hospital with them to help him and his grandfather. On the other hand, Vahid won a PhD scholarship to study abroad. For this reason, and despite the opposition of his wife (Fateme Daneshzad), Mr. Baharmest decides to marry his daughter Bita (Anahita Hemmati) to Vahid.
