Knock OutTony Khosla (Irrfan) is an investment banker who transfers the illegal money of politicians to the secret Swiss back accounts. He enters a phone booth to get his unscrupulous activities done without getting traced. Things take an ugly turn when he answers a call from an unknown number. On the other end of the phone is a sharp shooter, (Sanjay Dutt) who's hell-bent on redeeming Bachu (he prefers to call Tony so) of all his wrong doings. This soon becomes 'breaking news' thanks to reporter Nidhi (Kangna Ranaut). A tumultuous situation arises with the media, police, politicians, and revenue officials getting involved. While the first half is tolerable, the second half becomes a test of your patience. The interactions between the sharp shooter and Tony get banal. With the entire plot set primarily between these individuals you at least expect the dialogues to be engaging. But they fall flat. Moreover, even though there isn't a single song in the film, it still isn't enthralling.
