Nanda (Revathi) is in love with a successful architect Narendaran (Mohan Lal), both of whom are living in Bangalore. They get engaged and are all set to marry when tragedy strikes. While they are talking on top of a construction building, Narendran accidentally slips and falls down, dying instantly. Depressed Nanda escorts Narendran's corpse to his homeland in Kerala. To her surprise she sees Narendran's twin brother Krishnan Unni (Mohan Lal), who looks exactly like Narendran. She thinks Narendran is not dead and everyone is trying to fool her. Narendran's parents want Nanda to marry Unni but he is already in love with Bhadra (Shobana). Bhadra tries to commit suicide and this shakes Nanda, Bhadra's dear friend, and Unni. Not wanting to be a burden on anyone and truly missing Narendran, Nanda commits suicide. Narendran's ghost, moments before Nanda's suicide, tells Unni that he is going to take Nanda with him to heaven since he really needs her, even in death. Unni is unsure if he just had an illusion, but to the viewers, it shown that Narendran's ghost was present and actually talking to Unni.
