This is the story of the time when narcotics impair the brain; the time when a father’s hallucination becomes the dawn of his family’s demise by slicing them into pieces for a sin they have not committed; the time when revenge is the only reason to live. A series of violent and ruthless murders committed on the pretext of Deadly Sins (religion) brings Faramarz Afshar, a 32-year-old detective, into a case for which no easy conclusion can be found. “Murder in Tehran’s Alleys 2” is a tribute to David Fincher’s “Se7en”.
