[2] The film is about a young man who suffers from a neurological condition that results in partial retrograde amnesia and delusions due to a head injury and his subsequent recovery thanks to a woman and her psychiatrist father.

The group members are initially hostile to him but eventually decide to help him after Gautham pursues them aggressively and Hema realizes that he may be suffering from a neurological condition resulting in amnesia and delusions.

About six months earlier, he had travelled to a hill resort in Tamil Nadu for his research on musical patterns in the sounds of nature.

Gautham, in his hypnotic state, swears furiously to Rajashekar that he will avenge Gayathri's murder by capturing and killing the three men responsible.

Unable to make a decision on the next step forward, on Hema's suggestion, they decide to delay any action until Gautham's mother arrived from Malaysia.

Hema even wonders if it would be possible to bring Gautham back to normal by showing him enough care and affection that he forgets about Gayathri altogether.

Mohan Natarajan brought back together the team of the successful 1997 film, Kadhalukku Mariyadhai, in director Fazil and leading pair Vijay and Shalini with the venture.

Filming began in July 1999, after Vijay eventually completed the shooting for his previous romantic comedy Minsara Kanna (1999).

The reviewer added that the film was "subtle in scenic presentation and characterisation, suspense without melodrama and spontaneity in reactions are plusses", while mentioning that Shalini was "flawless" in her role.

The critic described that the "actor has shown laudable skill both in the way he has handled this complicated role and in expressing various shades of Gautham's tormented mind.

"[10] K. N. Vijiyan of New Straits Times noted that the film "offers something different from usual love stories and should appease Vijay's fans".
