Inspector Viktor, an eagle-eyed police officer who has been going through a personal crisis, is assigned to investigate the homicide of Nivetha, a young, unmarried woman.
Previously, Viktor and his wife, Geetha, are seen having a heated argument that gets violent. At present, Viktor scours the city police records for killings in the past that match with the killer's MO.
Viktor and Kishore meet Prabhakaran's wife and Keerthana's friend, amongst others. They get a lead on a red-coloured car that may belong to the killer.
Viktor and Kishore question possible suspects based on the killer's car details. Viktor also gets a surprise lead from the victims' phone-call histories.
