A penniless musician is unwittingly forced to trade places with a look-alike diamond merchant/thief causing a comedy of errors by everyone involved.

Bhola is a young musician who arrives in Bombay to try to make a living as a music player to get money for his crippled twin sister, Belu, to find a suitor to marry her. Ranjit Kamar is a wealthy businessman who moonlights as a diamond thief and smuggler who is the dead splitting image of Bhola. Bhola and Ranjit paths cross at a costume party Bhola unknowingly crashes in which Ranjit and his mistress Rita persuade the unsuspecting and naive country-bumkin Bhola to impersonate Ranjit for social engagements while the real Ranjit settles for his criminal activities, while an undercover policewoman pursues Bhola/Ranjit hoping to catch him in his latest thief.—Matthew Patay

Following a spate of jewel robberies, Bombay Police Commissioner assigns this matter to honest and diligent Police Inspector Pradhan. Pradhan enlists the help of three of his colleagues, namely Inspector Jagdish, Miss Malti Mehra, and Meena. He instructs them that they have to masquerade as a family, with Meena as the daughter, to lure the prime suspect in the robberies, Ranjit Kumar. Things go according to plan, and Ranjit is indeed attracted to Meena, who is now called Rita. But the robberies keep on escalating, and this time Ranjit Kumar has an alibi - he is with Rita, yet the police are baffled as to how can one person be at two places at the same time? And to complicate matters more, Meena falls in love with Ranjit, a move that could well jeopardize the entire mission.—rAjOo ([email protected])

Bhola, a young musician, leaves his small village to go to the big city, with dreams of making a dowry for his crippled sister, Belu. He leaves her behind with their abusive stepmother and loyal Doberman, Moti. When Bhola arrives in the big city he is almost immediately believed to be diamond thief and smuggler, Ramjit Kumar, who is currently under investigation by the local police department. Bhola is rushed into a party where everyone mistakes him for Ramjit, while the real Ramjit sits back and observes. Ramjit Kumar decides to train the naive Bhola, to take his place during the investigation - so that the police cannot link Ramjit to the elaborate heist he is about to commit. The police assign the beautiful young detective Meena to go undercover as Rita, a wealthy heiress and diamond connoisseur, with the intent of capturing Ramjit in the act! But instead, she finds herself getting to know the charms of Bhola (masquerading as Ramjit! The remainder of the film is a tale of mistaken identity, and close calls, interspersed with musical numbers, and a surprise ending and rescue involving Moti the Doberman who has unusual canine instincts.—Eleonore Thomas
