One day just by chance he sees his duplicate in a very costly imported car. He follows the man on a bicycle and ultimately losses the track - but not for long, luck favours him and he comes to know that the man is a well to do doctor - Circumstances too favour him and very soon and quite safely he implants himself as doctor and henceforth laugh, roit starts - non-stop. Scene after scene keeps you on edge. Can you imagine when a street gonda is placed on doctor's chair what will happen next?
Every scene is revealed in such a hilarious manner that one bursts into laughter.
The doctor who was being wooed by a millionaire's successfully is just marvelled on seeing the doctor in reverse mood and responds favourably.

This is not just a comedy of errors but also a hilarious story of mistaken identity. A life time chance one cannot afford to miss deliberately.
