Diljalaa (1987)

Mamta lives a middle-class lifestyle in Bombay with her widower dad Ratanmuni Gupta, who works as a Manager with Sharda Chemicals while she studies in Lovedale College in Manori. Her dad wants her to marry a naive, semi-senile Munna, the only son of widowed Sharda, his employer. On the day of the engagement she humiliates her dad, Munna, and Sharda and refuses to marry Munna. Shortly thereafter, a number of young children die after being injected with medication from Sharda Chemicals. Yhe Police investigate and arrest Sharda, while Munna kills himself. Ratanmuni and his partners, D.S. Mittal, Mehra, Radhey, and Shyam, take over Sharda Chemicals and re-name it Friends Chemicals. Sometime later when Mamta returns from Manori, her dad introduces her to wealthy Mrs. Modi, who wants her to wed her only son, Azad. Azad and Mamta approve of each other, meet, and get intimate. On the day of their engagement, many surprises await Mamta as she finds out that the man she got intimate with is not the real Azad, while the real Azad and his mom will have nothing to do with a now-characterless Mamta.
