Dev and Chandni are childhood friends, hailing from Allahabad. Dev's father is the Mahant (chief priest) of a temple known for its hidden treasure. Dev's father is arrested for stealing the idol's jewellery and his wife is accused of being a witch. They are killed by a mysterious person after which Chandni's father Yash Narayana Vashisht becomes the Mahant. Dev escapes with his younger brother Meeku, and while travelling by train, he is forced to throw his brother out to save him from a mob.
Dev has returned to Allahabad disguised as Advay Singh Raizada. Holding Chandni and her family responsible for what his family had to go through and his separation from his brother, he plans to take revenge. He buys the house the Vashishts are living in but lets them stay there. Meanwhile, Chandni's wedding is fixed to PP, a sleazy man whose family is going to pay off her stepmother's debt. Advay rescues her from her fiance's behaviour on several occasions but not without insulting her each time. Chandni is confused about why he hates her so much. He further disrupts her wedding and forcibly marries her by blackmailing her that he will reveal the truth of her illegitimate child who currently stays in an orphanage. Chandni agrees to save the respect of her family but doesn't tell Advay that the child is actually her sister's.
Advay exposes this anyway at their reception party in order to spoil the Vashisht family's reputation. He throws them out of the house but his grandmother shelters Chandni. She believes in Chandni's innocence and asks her never to leave Advay no matter what happens even though Advay has been emotionally abusive and misogynistic. Eventually, the truth finally comes out before Chandni and Advay. Chandni realises Advay is her long lost childhood friend Dev and Advay discovers that Chandni has been innocent all along. Chandni has her stepmother, the real culprit, arrested and seeks out Miku, reuniting him with Advay. Miku falls in love with Chandni's sister Shikha and the family plans to get them married.
