Shabor is all set to come back with a darker storyline. Shabor series in Arindam Sil's direction never shied away from bringing the not-so-explored side of the criminal mind. Based on Shirshendu Mukhopadhyay's 'Projapotir Mrityu O Punorjonmo', Sil's latest endeavor 'Red Cycle' will be shot in Lucknow. Shabor with his assistant Nanda and Inspector Sanjeeb will visit Lucknow receiving a special invitation to solve a crime. "90% crime in contemporary world is related with sexuality. Crimes are increasing in sex sites. I've modified the story a bit and doubled the pace from the previous films. Sexuality will have a pivotal role in the film," said Arindam. The film will go on the floor on 5th September.
