The film starts off indicating the parallels of the story with that of Adam & Eve. Here, Adam is Ranjeet (Sanjeev Kumar), Eve is Sharda (Vidya Sinha) while the apple is Nirmala. Ranjeet is newly employed in a company, whose pay scales can be gauged from the fact that he goes to work on a bicycle. However, this bicycle itself brings him face-to-face with Sharda, when he bumps into her by accident. Sharda's bicycle gets badly damaged & Ranjeet drops her off. Th same evening, Ranjeet goes to the wedding of his friend (Asrani), a co-worker & a poet. Sharda is also present at the ceremony. Sharda & Ranjeet's love blossoms from there & soon they get married.

In the course of a few years, Ranjeet becomes a father, buys a car & rises to be the Sales Manager of the company. Sharda & Ranjeet are still living in marital bliss. That is, until Nirmala, Ranjeet's new secretary, shows up. Ranjeet is inexplicably attracted to Nirmala. She is an honest girl who is trying to make two ends meet. She is much more beautiful compared to Sharda. But most of all, she knows nothing about Ranjeet's true intentions & his married life.

Ranjeet is initially upset with his thoughts about her, but finally gives in. He carefully plans his further steps. He pretends to be the helpless grieving husband of a cancer-stricken wife, who won't live much longer. Nirmala feels sorry for him, thus making it easier for him to get close to her. Nobody, not Sharda, not even his closest friend, suspects a thing. One day, Ranjeet bluffs to Sharda that he will be late coming home as he has a meeting. He takes Nirmala out to dinner.

Next day, Sharda finds Nirmala's handkerchief, with lipstick marks on it, in Ranjeet's pocket. She immediately confronts Ranjeet, who makes up a story about a co-worker whose handkerchief he may have accidentally taken. Sharda reluctantly believes him. Ranjeet decides to take his next steps more carefully. Sharda too starts thinking that her fears were unfounded. Ranjeet makes even more interesting back up plans: He prepares two books of poetry, professing his love. The poems are the same in both, only one book contains Nirmala's name, and the other contains Sharda's.

Ranjeet keeps on taking Nirmala to luncheons & dinners, without Sharda's knowledge. The turning point comes when Sharda sees him in a hotel with Nirmala. She later asks him about his meeting, about which the clueless Ranjeet lies. Sharda's fears are confirmed. She starts spying on him & Nirmala, taking incriminating pictures. After sufficient evidence is obtained, she secretly meets Nirmala, posing as a journalist.

Nirmala thinks Sharda intends to blackmail her. But Sharda reassures her that she won't. When Nirmala tells her about Ranjeet & his ailing wife, Sharda reveals her true identity. Sharda also finds the two diaries. Meanwhile, Ranjeet gets another promotion & comes home happily to tell his wife about it. Sharda coolly tells him that he is busted. Ranjeet does not know what has hit him. He turns around, only to see Nirmala behind him. Sharda tells him that she is leaving him & the divorce papers will be soon sent to him. Sharda & Nirmala console each other. Ranjeet calls upon his friend & lies that Nirmala has said some malicious lies to Sharda about him.

Ranjeet's friend sides with him & lies about Nirmala's character. Sharda exposes Ranjeet in front of him as well, with help of the evidence she has collected. Sharda tells Ranjeet to choose either her or Nirmala. Ranjeet quietly gives Nirmala some money & lies to her, in a last-ditch attempt at damage control. But honest Nirmala returns the money to Sharda, making things even worse for Ranjeet. Sharda prepares to walk out on Ranjeet.

Meanwhile, Nirmala also resigns & leaves his life forever. Everything looks bleak for Ranjeet. As Sharda is about to leave home, her innocent son asks what is happening. Just for his sake, Ranjeet & Sharda try to reconcile. Life comes back on track. But soon another secretary (Parveen Babi) joins the office & Ranjeet tries to resort to his antics once more. As if by coincidence, Ranjeet's friend suddenly walks in & Ranjeet backs off, taking this as a warning.
