Bol Radha Bol (1992)

Kishan Malhotra finds his life turned upside down, when he returns home one day to find that his place has been taken over by a look-alike imposter. When he attempts to assert his identity, no one including his very own mother, or even his dog, believes him. The only person he can trust now is a young lady named Radha, and together they embark on a task of finding out the truth; who is behind this conspiracy, and if at all it is possible for him to get his life back together again.
