The story revolves around Nageen (Hiba Bukhari), who hails from a lower middle class background, and Sultan Durrani (Danish Taimoor), a wealthy businessman who hails from a political background. Sultan lost his parents at a very young age and lived with his grandmother Bi Jaan (Ismat Zaidi) ever since. Nageen lives with her sister Nuzhat (Faiza Gillani), brother-in-law Rashid (Noor-ul-Hassan) and Rashid's mother. Nageen only lands menial jobs because she does not have a degree, and is hired as a bus hostess at a private bus company.

After a few days, Sultan forcefully tries to put a ring on Nageen's fingers but she refuses and slaps him. Narmeen's secret agent records a video and it goes viral on social media.
