The movie opens in September 1983 when a roadside sweeper finds a body of young homeless boy with his head crushed in Sion, Mumbai. There is a large stone nearby & the body along with the area around it is covered with sindoor. When the investigating officer Sanjay Shelar (Kay Kay Menon) ends up killing up one of the suspects while in custody, he is immediately suspended by his senior officer Satam (Vikram Gokhale), the case is reassigned to Sanjay’s rival officer Kedar (Arbaaz Khan) & the murder is brushed off as a one off occurrence which doesn’t need much attention. When the series of murders doesn’t seize, Satam allows Sanjay to carry on his own unofficial investigation, which if successful would result in his reinstating into the police force. Sanjay collects some evidence with the help a police constable (Virendra Saxena) & from some of his informants on the street. His observations place all the murders having occurred on Tuesdays & Saturdays after midnight. Soon enough he’s walking the streets between Matunga & Sion looking for the killer & clues. However since Kedar is unaware of the unofficial investigation, Sanjay’s late night excursions soon place him under suspicion as the killer. Each time Sanjay seems to be on the verge of solving the case & nabbing the killer, he slips away & soon enough seems to know everything about Sanjay & his whereabouts. Thus the hunter becomes the hunted.
