Orphaned Raju, in the company of four elephants, has to perform with them at street corners, in order to survive. The back-story is that as an orphan, they have saved his life from a leopard. In time, he makes it big, and starts Pyar Ki Duniya (The World of Love), a zoo in which various wild animals reside along with his elephants, among whom Ramu is closest to him. Slowly he amasses a fortune, and is able to build his own private zoo, housing tigers, lions, bears, and of course the four elephants. He treats all the animals as his friends. He meets with Tanu, and both fall in love. Tanu's rich dad, Ratanlal, is opposed to this alliance, but subsequently relents, and permits the young couple to get married. However, trouble looms soon after as Tanu feels neglected. Things worsen when their child is born, and Tanu, fearing physical harm to her child from the elephants, tells Raju to choose between the elephants and his family. When Raju chooses his lifelong friends over wife and son, Ramu decides to bring the estranged couple together, but to save the family and the child from the villainous Sarwan Kumar, he sacrifices his life.
