The story revolves around three married couples. One couple, Tripathi (Sanjeev Kumar) and his wife Mary are happily married. The second couple, Geeta (Shabana Azmi) and Vinod (Vinod Mehra) live in Vinod's mother’s house. Theirs is an unhappy marriage with Vinod spending a lot of time with Leena (Prema Narayan), and frequenting late and all-night parties. His wife patiently awaits his return every night. The third couple is that of Shobha (Moushumi Chatterjee), a very jealous and possessive woman and Micky Kapoor (Jeetendra). Theirs is a seemingly happy marriage. One day when Shobha sees her husband and Radha (Tanuja) together, she thinks they are having an affair, and starts pestering Vicky about it. Suddenly their lives are turned upside down. Meanwhile, Vinod decides to leave Geeta, but meets with an accident and during his recovery period Geeta proves how important she is for him. Shobha leaves her husband and at this juncture, Tripathi steps in to mend the couple. Whether Tripathi is successful in mending these couples forms the rest of the story.
