Karthik (Prithviraj Sukumaran) and Viji (Prakash Raj) are close friends, who are keyboard players in music director Vidyasagar (music director)’s team. They are brilliant in their work of re-recording and background scores. They are fun-loving, witty and share a great rapport. They come to live in an apartment complex building where they meet a handful of interesting people. Their neighbour and flat secretary, Ananthakrishnan (Brahmanandam) is not too happy about Karthik and Viji occupying the flat and asks him to vacate as bachelors are not allowed to live there. Preethi (Neelima Rani), a girl from one of those apartments, is head over heels in love with Karthik.
