Plot

A wedding advertisement of leading businesswoman Monika with a gentleman brings up a flurry of girls to the police, each one of them claiming the young groom in the picture to be their husband. Puzzled at first, the police slowly realises that they are dealing with a clever and elaborate con artist and womaniser who impresses beautiful girls with elaborate bluffs to a quick marriage and escapes with their money/jewelry after sleeping with them. The police sends out a look out notice with the photo and the man is shown outsmarting the police narrowly on many tough situations, but once the bus he is in gets into an accident sending everyone on board unconscious, and he is inevitably picked up by the police from the hospital.
