Himalay Putra (the son of the Himalayas) starts with the love story of Suraj (Vinod Khanna) and Seema (Hema Malini). Seema being the daughter of a rich businessman and Suraj being a police inspector with a modest income, are destined to face the objection of Seema's father (Amrish Puri) to their marriage. Amrish creates misunderstanding in Seema's heart for Suraj and she starts looking upon him as a greedy person who discarded her love for the sake of money. But the problem is that she has already got pregnant through him and after the demise of her father, she moves to the region of the Himalayas, giving birth to Abhay (Akshaye Khanna). Abhay grows up misunderstanding his father by learning his mother's version of the past events. He falls in love with Esha (Anjala Zaveri) who is the daughter of their neighbor - Major Mathur (Satish Shah) but love is less important for him. What is more important for him is to locate his father and settle scores with him for his mother's sorrows.
