Aruna Khosla and Ajay Chandra meet each other at a party and are immediately taken with each other. Ajay is a graduate and wonderful singer. Frustrating his mother, he does not want to get a job, but find a way to get rich quick. He plans to purchase, repair and sell galvanometers. A man named Anokhelal helps him in this endeavour.
When Aruna invites Ajay to her house, he is made acutely conscious of their difference in social status. He lies to her, telling her that he is a well off businessman. To keep up the pretence, he borrows his friend Prakash’s clothes and car. The lies start snowballing as Ajay has to tell one fib after another to maintain his façade.
Ajay borrows large sums of money from Prakash to start his business. When a big competitor offers to buy him out, he refuses to do so. Unbeknownst to him the competitor already knows Anokhelal. Meanwhile Ajay is introduced to Aruna’s father who is a lawyer. Their relationship progresses and soon there is talk of marriage. Ajay feels guilty about lying to Aruna but sees no way to extricate himself from the pit he has dug himself into.
Ajay’s business starts failing badly, as his consignments keep getting returned due to faulty parts. Anokhelal becomes elusive and fails to live up to his promises. Driven into debt, Ajay realises his rash decisions have caused his downfall. His friend Prakash remains ever supportive. At this juncture, Aruna’s father realizes the truth about Ajay. Ajay confesses everything to Aruna who is willing to forgive him. But Mr Khosla is not so easily convinced. When one of Ajay’s former customers comes to him looking to prosecute Ajay for cheating him, he takes Ajay to court. Ajay, meanwhile, has undergone a transformation. Inspired by his mother’s words, he repairs all the galvanometers himself and returns them. In court, Ajay’s lawyer exposes the machinations of his competitor who had bribed Anokhelal to sabotage the business. His lawyer argues that Ajay is a victim of a monopolistic system which favours the big businessman. When Ajay returns all the galvanometers the case is taken back. Ajay learns a valuable lesson about the importance of hard work.
