Anand(Jaishankar), a doctor, is in love with Rama while Latha, a nurse and also, the daughter of the chief of the hospital(Ramdas) is in love with him. One rainy night, Anand sees a woman(Jayalalitha) in a white sari standing in the middle of the road. He offers to drop her off but things get stranger when she get in. The windshield wipers stop working but she seems to be able to see the road even when visibility is virtually zero due to the rain. She gets off at the cemetery, whose gate opens automatically, and disappears inside. A few nights later, Anand gets a call from an old man, who takes him to a palatial house in ruins. Here he sees the same woman lying dead on her bed. But when he brings the police, she has disappeared. Surprisingly, the police inform him that other doctors too had reported similar experiences. Meanwhile, Rama is killed and Anand weds Sandhya(Jayalalitha) on the insistence of his mother. He is shocked when he sees that Sandhya is a mirror image of the woman who has been haunting him.

The movie works on two levels, a horror movie and a suspense thriller, and is an unqualified success on both counts. Scenes like the one where the old man takes Jaishanker to his house are rather creepy. The black and white photography actually works to heighten the atmosphere, with the candle flame casting ominous shadows on the wall of the house.

The director also seems to know how to maintain the suspense. He keeps introducing new characters as we go along, each of them revealing a little bit more about the plot. This keeps us constantly guessing as to what could be happening and that is always a sure sign of involvement in the movie. When the mystery is unravelled, the pieces of the puzzle fit together very nicely. The identities of the villains(and in one case, a good guy) are mostly surprising. As far as I could see, there were no gaping plot holes or questions left unanswered.

The multitude of songs and the unfunny comedy are unnecessary speedbumps to the flow of the story. Naane Varuvaen... is haunting and melodious but none of the other songs sound good. The comedy, which involves Manorama and the servant in Jaishankar's house, raises no laughs and is painful most of the time. Thus, the comedy and song sequences allow the tension to ebb at key points in the story. Elimination or atleast trimming down of these portions might have transformed the movie into an edge-of-your-seat thriller.

Jaishanker slips out of his usual 'James Bond' persona to play a man who is as confused as we are by the happenings around him. He is effective at conveying his helplessness and inability to makes others understand and believe him. Jayalalitha plays both the ghost and the confused wife well. But the two actresses who play Rama and Latha appear rather artificial. P.S.Veerappa, who is the producer of the film, appears as a policeman while Aanandhan, father of 'Disco' Shanthi, plays Jaishankar's cousin.
