Ghaneema invites her three granddaughters, Sarah, Lamia, and Manahel, to stay in her house for a year after their father's death in order to choose an heiress from among them and stipulates that they get a job as a precondition for having the inheritance.
The three granddaughters succeed in getting jobs, and are surprised when Ghaneema loses her ring, which later turns out to be a test for them.
Ghaneema decides to hire Duaa, the daughter of her maid, Nachmia, for a job in the company and reveals the second condition for her granddaughters, which is marriage within a year.
Ghaneema asks Saud to follow up on the company's theft investigation. As Sarah agrees with Khaled to propose to her, he reveals his refusal to marry her because Sarah's mother is being treated in a mental institution, while Lamia gets to know the teacher Ahmed in order for him to marry her.
Sarah's psychological state is affected by Khaled's situation with her, and she gets to know Mahmoud. Saud asks Manahel to propose marriage to her, and he agrees with Mona to falsely claim that he is her brother.
Mahmoud tries to get close to Sarah without telling her that he is Duaa's husband, while Lamia discovers that Ahmed is the son of Nachmia. Ghaneema fires Saud from the company for stealing money and tells Manahel that Adel is still alive.
Lamia tells Ghaneema the truth about Nachmia and her agreement with her son Ahmed, and Sarah marries Mansour.
Lamia accepts Ahmed's apology and marries him. Sarah gets married as well, and Ghaneema decides to choose her heiress.
