A fantastic investigative thriller that keeps you hooked from start to the very end. The film starts with Rahman, a retired policeman talking about a case that he handled. A suicide happens early morning which Rahman starts to investigate. Meanwhile, a girl goes missing. There is also a hit and run case involving three boys. How Rahman goes about investigating with the help of a couple of constables and did he solve the case forms the basic plot. The movie is flawless until the very end (though the end has a few unanswered questions). The background music, cinematography and acting is top class. The tempo builds from the very first scene. It is such a relief to see such a good tamil film after almost a month of two filled with duds. A brilliant film from director Karthick Naren.
