Zubeida (Savera Nadeem), more commonly known as Badi Aapa, is the central character of the telenovela who possesses a rigid and dictatorial nature, and her husband, Farmaan (Noman Ijaz), likes to stay out of her way. Zubeida's only daughter, Sharmeen (Sarah Khan), is in love with a man named Essa (Fahad Mirza) and wants to marry him, but Zubeida doesn't agree to the union. Sharmeen decides that the only way to convince her mother is to talk to her uncle, Ghazanfar (Waqas Khan), who is the only man Zubeida listens to because Zubeida and Ghazanfar used to like each other when they were young. But at the same time, Sharmeen gets to know that her mother has already decided to get her married to Ghazanfar's son, Adeel (Mustafa Changazi), who happens to be Zubeida's nephew. Adeel had always loved Sharmeen. But as Adeel's mother, Firdouz (Arjumand Rahim), i.e., Zubeida's younger sister, doesn't want him to marry Sharmeen, Adeel refuses, and Zubeida gets angry with her younger sister. Soon Zubeida comes to know that her husband has secretly gotten married for the second time to a lady, Neelam (Ayesha Khan Jr).
Zubeida believes that Ghanzanfar is still in love with her and will leave his family for her, so she demands a divorce. Farmaan begs her to stay, but Zubeida insists and tells him about Ghanzanfar still loving her.
On her way to Ghanzanfar, Zubeida recounts the loving moments shared between the two. On arrival at her sister's home, she's surprised that her sister is back and that not only does Ghanzanfar care for his wife, but he only sees Zubeida as his wife's sister and nothing more. Zubeida, embarrassed, makes her excuses and leaves to go back home.
On arrival at home, her husband tells her he has already divorced her and is moving out with Neelam.
