Kunal, a respected teacher in a Christian school, is arrested on false charges because he refuses to teach the Biblical story of creation before teaching Darwin's theory of evolution. He is accused of being an apostate and a Maoist. The story then moves to a courtroom where he pleads "not guilty" since he strongly feels that he is a science teacher and it is his responsibility to impart knowledge, not to preach religion and superstition. Hats off to writer-director #SaibalMitra for handling a complex theme with such maturity. Naseeruddin Shah and Soumitra Chatterjee are brilliant. Bengali film #AHolyConspiracy is something Bollywood would never dare to make. Running time needs to be reduced by 20 minutes. There are limited shows in mumbai and there is hardly any publicity. Do watch it. Rating 4/5.
