Nibunan (2017)

Ranjith Kalidoss is a sharp, experienced officer leading a small team that handles difficult crimes. A series of murders begins in which each victim is left with a strange, deliberate clue, almost like a message, and it soon becomes clear that the killer is playing a game with the police and with Ranjith in particular. Nibunan ('expert') was Arjun's 150th film and was made simultaneously in Kannada as Vismaya. Director Arun Vaidyanathan, who earlier made Achamundu! Achamundu!, gives it the shape of a procedural thriller.
