Amar (Jeetendra) and Bihari (Shatrughan Sinha) are more brothers than friends. With Amar's mother dead and his wealthy businessman father largely absent, Bihari's mother raises Amar like a member of her poor but loving family. The two friends remain close as they grow up and marry within their class. But then Amar's father reappears. Strongly disapproving of his son's friendship, he succeeds in destroying it, and Bihari's sister must try to repair the tattered bond between her "brothers."
