Jeetu, the son of retired teacher Jaidev Prasad, is constantly getting himself and his father into trouble because of his inability to properly manage money and has run many failed businesses. Plunging them both into debt, Jeetu breaks off his engagement with his promised fiancé, Pooja and decides to commit suicide by throwing himself into the sea. Jeetu thinks that by killing himself, he can do something right for once since his father can use the money from his life insurance to pay off his debts.However, it does not go as planned and Jeetu is found tangled in some nets by a pair of fishermen, Gundya and Bandya. Gundya owes money to a Gujarati businessman, Prabhat Singh Chauhan. They find a note containing people's names with the amount written next to the name in Jeetu's pocket, which makes them mistakenly think Jeetu is rich and has lent money to these people, rather than in debt. Jeetu does not want to reveal too much, and therefore pretends to be mute and deaf. Back home, Jeetu's family is denied insurance, stating unconfirmed death, putting them in a difficult situation of repaying Jeetu debts. Prabhat takes away Gundya's boat, the only source of Gundya's income so that he pays back the money he owes him. The two fishermen visit Prabhat's house to request back their boat, only to be asked by Prabhat to leave something of value in return as a guarantee. Gundya cunningly makes Prabhat believe that Jeetu is his loving nephew and leaves both Jeetu and Bandya as the guarantee. Later, it is revealed that Prabhat's niece Shruti is mute too, but not deaf. Her overprotective brother Mangal wants her to get married, however, her muteness makes her an undesirable match. One night, Jeetu gets drunk, and begins to sing but is caught by Shruti and her cousin Meenakshi who hear him. They promise to keep his secret but in return, he must do something for Shruti. A greedy bridegroom is interested in marrying Shruti only for her wealth; so Meenakshi tricks Jeetu into pretending to be Shruti's lover, which eventually results in the marriage being broken off. Mangal arrives and finds Jeetu with a love note for Shruti that Meenakshi wrote. Not realising Jeetu is pretending to be mute and deaf, Mangal attacks him and only stops upon being told of Jeetu supposed disability. Regretful, Mangal gives Jeetu a job in his business and Prabhat extends Gundya's loan time. Meenakshi finds out that Jeetu is in debt and she begins to distrust him after learning about the troubles his debts are causing his family. Jeetu eventually finds out that since his body has not been found, his family is still being hassled for his debts as the insurers have not paid. Jeetu is involved in a car crash with Prabhat who, at the time, was carrying a lot of money. Meenakshi tells the police about her suspicions and they beat Jeetu mercilessly. Her and Shruti's views about him change however when Prabhat announces that Jeetu was the one that saved him and took him to hospital. A remorseful Shruti and Meenakshi, trick Prabhat into giving them money which they send to Jeetu's village through Bandya to repay his debts by having Bandya pretend to be Jeetu business partner. Bandya returns from the village and tells Jeetu that Pooja is married now. Unaware that Pooja believing herself to be Jeetu's widow, is living with Jeetu's family. At the same time, Shruti confesses her love for Jeetu. Mangal finds out about the romance and requests Jeetu marry Shruti after Jeetu reveals he is not deaf and mute.
