Iraj, Mr. Javanmard's secretary, goes to Mr. Paymard's house with a letter from Mr. Javanmard to propose to his daughter, Giti, for Farrokh, Mr. Javanmard's son. Mehraghdas, Mr. Paymard's wife, opposes the marriage because they don't know Farrokh. To test Farrokh, the couple introduces three girls as their daughters so that Farrokh can identify the real daughter among them.
