Anoop (Dharmendra) is a struggling writer. One day he meets with wealthy and beautiful Seema (Hema Malini) and both fall in love. When Seema?s brother Rajan Choudhury (Pran) finds out, he is angered and forbids Seema to see Anoop again. On the other hand Anoop?s sister, Rekha (Aruna Irani), and Rajan?s brother-in-law Mahesh (Mehmood) have also fallen in love with each other.
This angers Rajan even more and he turns Mahesh out of his house. Rajan finds out that Anoop has authored a book called "Naya Zamana", and decides to publish it and sell it under his name. Anoop and Seema find out when the book hits the stalls and is a big hit. Rajan is unapologetic. Rajan then tries to evict the poor people living in small tenements with Anoop and his mother (Lalita Pawar), but Anoop and Seema intervene, and as a result Rajan orders the tenements to be burnt secretly by his henchman Sitaram (Jankidas).
