Bengali film-maker Anindo Banerjee's first film (since his previous film has been stalled for some reason), Chaplin is about a man Bangshi who is a a very big fan of the legendary Charles Chaplin. Bangshi hails from a lower middle class colony and stays with his son. He has grown up watching films of Chaplin and wanting to be like Chaplin.
In fact Bangshi earns his living by imitating Chaplin and trying to impersonate him at small programs and events and to walk and talk like Chaplin is the only thing he knows and can perform best. His son Nemoa sees young kids like him celebrating their birthdays in style where his father performs and he also desires to do the same.
Since his father can’t afford to do so, there is clash between the father and son. The father is also looking for his first break which does take place ultimately. How the character of Chaplin becomes more relevant than the actors remains to be seen.
