DCP Karthikeyan (Arjun) is given the task to investigate a gruesome murder in Chennai. One fine day, Prabhakaran (Vijay Antony) surrenders at the police station and confesses to committing the crime. However, the case isn’t as open-and-shut as it seems and a determined Karthikeyan sets out in search of the truth. Has Prabhakaran committed the murder or is he innocent? To know that and more, you need to watch Kolaigaran.
The film largely revolves around four characters and the lead actors in Arjun Sarja and Vijay Antony have done an impressive job in carrying the film on their shoulders. For most parts of the narrative, it’s a duel between the two actors and their contrasting performances give the film the much-needed boost.
