Nigahen: Nagina Part II (1989)

After the tragic deaths of his son, Ajit and daughter-in-law, Rajni, Raja Saheb decides to educate his grand-daughter, Neelam, in the city. Years later, Neelam has grown up and returns temporarily to their rural palatial home. Raja Saheb would like her to live there, and look after the business, but she refuses. Then she meets with Anand, and everything changes for her overnight. Both of them fall in love, and would like to get married. Anand is introduced to Raja Saheb, and Neelam is introduced to Anand's mom, Shanti. Both approve of this couple and plans are set for the marriage to take place. When Neelam does not know is that Anand is not who he claims to be - but in reality was a snake kept in captivity by Tantrik Goraknath, who wants to possess a priceless diamond stone called "Mani", and Neelam is the only one who knows it's location. And Goraknath, unlike his mentor, Bhairavnath, has ensured that no one will stand in his way when he obtains the Mani.
