Gupi (Prosenjit Chatterjee) is a small-time conman in love with Madhu (Richa Gangopadhyay), a pretty woman whom he met at a wedding he wasn't invited to. Into this picture world enters six-year-old Osmita (Baby Titli), who inexplicably believes Gupi to be her father. And if this wasn't bad enough, Gupi becomes the object of a series of life-threatening attacks by a gang of criminals who seem to know something he doesn't.
While trying desperately to save his life and love, Gupi stumbles upon a deadly secret. A secret that will take him to a small town named Debgarh: A town terrorized by its ruthless MLA and the mafia he controls; a town whose inhabitants' only hope for redemption is Gupi. Later he learns that ACP Bikram Singha Roy (Prosenjit Chatterjee), his look alike, is in danger from criminals. What will the future hold in store for these two men who share a remarkable resemblance?
