Diljalaa

Widowed multi-millionaire Sharda lives with an only son, Munna; she is also the proprietor of a factory called, "Sharda Chemicals". Sharda arranges Munna's marriage with the factory's general manager, Ratanmuni Gupta's daughter, Mamta who is currently pursuing studies at Lovedale College in Manori. On the day of the engagement, Mamta insults her dad, Munna, and Sharda in the presence of a huge gathering, so the marriage plans get canceled. Then several children get killed after receiving a vaccine manufactured and marketed by, "Sharda Chemicals," prompting the police to arrest Sharda, who is convicted of the crime in a court. Eventually Munna is killed by Gupta, who with his friends D.S. Mittal, Mehra, Radhey, and Shyam takes over the family's assets and renames the factory "Friends Chemicals." Gupta then arranges to get Mamta married to wealthy Mrs. Modi's son Azad, but before the marriage Mamta gets pregnant by a man disguised as Azad, and Mrs. Modi cancels the wedding plans. Gupta began to face many business challenges; Munna actually survived the murder attempt and is out to destroy Gupta and the others.
