Manohar, (R. Madhavan),moves into a new apartment, 13B, on the 13th floor with his family, fulfilling his life's biggest dream. But they encounter a series of small but strange incidents (such as milk getting spoiled), which are regarded as inauspicious by his family but shrugged off by an excited Manohar. The elevator in the apartment works for everyone in the building except Manohar, which bothers him.
