This disheartens Sita, who grabs her black Fiat, drives recklessly to kill herself, but ends up hitting Jyoti, who is about to get married and is the sister of Arjun. She is followed by Lata in a white Hindustan Ambassador, who also bypasses the dying Jyoti, but is unable to stop Sita from killing herself by leaping from a cliff. Lata blames herself for the death of Sita and loses her mental balance. Meanwhile, Arjun vows to revenge his sister Jyoti's death, joins the gang of villains in Dr. Prashant's gang, and by a series of planned events, enters the Rai household as husband of Lata. He plans to kill Lata with Dr. Prashant, to whom he has pledged the Rai family empire in the deal. But fate has other things in store for him when he discovers the love of Lata and his misunderstandings. Before he can recover from his false Stupor, he is trapped by police officer Karan who also loves Lata, and taken into custody, for conspiracy.

The film ends in Kali temple, where Lata is taken for human sacrifice by the goons of Dr. Prashant, where in a scuffle and action, victory over evil prevails, but Karan loses his life in an attempt to save Arjun, who is a reformed man and dear to Lata.
