A father on his deathbed stipulates that after his death, his two children will inherit his property on the condition that his grandchildren marry each other and have children. The two brothers try to convince their children to marry each other with Ramin's help: but Mehri, the cousin, and Mehdi, the cousin, each refuse to do so, imagining that the other has agreed to marry them with the intention of acquiring wealth. On the one hand, Mehdi is tied to a singer, and on the other hand, Mehri is interested in a young man who works as an assistant cook in their house. Mehri and Mehdi agree to a temporary marriage to get rid of their fathers, until each of them, after ridiculous adventures, realizes their love for the other and happily starts a new life.
