In a contemporary interpretation of war torn Calcutta during the 1940's, the film follows the first adventure of Byomkesh (Sushant Singh Rajput), fresh out of college, as he pits himself against an evil genius who is out to destroy the world. It's his wits against the most villainous arch criminal the world has seen, in a world of murder, international political intrigue and seduction.

So finally, Byomkesh comes to Bollywood!! A well-scripted movie with an original story.Just the base is taken from the original work.The movie seems a bit slow at times but overall, you remain glued to your seats in the anticipation of what's coming next. Its not just another Bollywood thriller. The movie demands the attention of the viewer. In the end, you want for more! Sushant has played the role brilliantly. Other actors are commendable too.There are no irritating songs in the movie, and the dark background music adds to the mystery. Kudos to Dibakar Bannerjee for directing and YRF for producing this movie. And the story is not yet over.... there's more to come!
