Cast
Bhola (Rajesh Khanna) 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 (Naaz), to find a suitor to marry her. Ranjit Kamar (Rajesh Khanna in a double role) is a wealthy businessman who moonlights as a diamond thief and smuggler who is the dead spliting image of Bhola. Bhola's and Ranjit's paths cross at a costume party Bhola unknowingly crashes in which Ranjit and his mistress Rita (Mumtaz) persuade the unsuspecting and naive country-bumkin Bhola to impersonate Ranjit for social engagements while the real Ranjit settles for his criminal activities, while a undercover police woman persues Bhola/Ranjit hoping to catch him in his latest robbery.
