The series follows the story of a resilient girl, Jhanak. Her life takes a drastic turn when her mother dies and she is forced to marry her cousin Arshi's fiancé, Aniruddh, to escape from her obsessive stalker, Tejas, who is twice her age. Jhanak struggles to survive in the world all by herself, so she is taken by Aniruddh to his house. At the Bose House, she faces constant insults from Aniruddh's family members as she works as a maid in the house.
Shrishti, her maternal aunt, hates her to the core and suspects that an affair is brewing between Jhanak and Aniruddh. Eventually, Jhanak and Aniruddh's marriage is revealed to everyone and they are forced to divorce. Jhanak moves away to Mumbai to start her career as a dancer, while Arshi and Aniruddh get married. However, fate keeps intertwining Jhanak and Aniruddh's life, where they finally confess their love for one another.
Nonetheless, Jhanak is targeted by Srishti and Tejas and she is presumed dead to the world. After her presumed death, Arshi and Aniruddh try to salvage their relationship, but Aniruddh can't help but miss Jhanak. Jhanak is rescued by Brijbhushan's dopplegänger, who introduces himself as Kulbhushan. However, a twist in Jhanak's life comes when she finds out that the one who rescued her is the real Brijbhushan and her biological father. Jhanak finds out the dark history and truth revolving Brijbhushan, Kulbhushan, Srishti and Urvashi.
Years ago, Brijbhushan was Srishti and Urvashi's dance teacher. Srishti, in a bid to climb the ladder of success quickly, seduced Brijbhushan and got married with him. Brijbhushan was deeply in love, but Srishti left him for the more successful Vinayak and married him and had a daughter, Arshi. After Srishti's betrayal, Brijbhushan is broken and Urvashi consoles him and becomes his pillar of support. However, Srishti, jealous of the growing closeness between Brijbhushan and Urvashi, comes back to him. Brijbhushan was blinded by love so he once again accepted Srishti, who then gave birth to their daughter, Jhanak. Srishti, with the help of Kulbhushan, gets Brijbhushan out of her way, because she is afraid that her name and fame will be tarnished. Kulbhushan believes he has murdered Brijbhushan and steals his identity and becomes Brijbhushan for the world. Urvashi, unaware about the identity switch, is ousted by Kulbhushan from the house along with Jhanak. Srishti spreads rumors that Urvashi has relations with Brijbhushan and gave birth to his daughter. Srishti's lies becomes the truth in everyone's eyes and Urvashi accepts Jhanak as her own child to protect Jhanak.
After revealing the past, Brijbhushan compels Jhanak to seek revenge against everyone that has wronged her and Urvashi. Thus, Jhanak returns as Nutan to finally expose Srishti and Kulbhushan's truth.
