Kannukkul Nilavu 2000

In Pondicherry, Gautham Prabhakar, a meticulous musicologist, sets out to find Gayathri, a local woman he believes is his lover, and seeks help from a tight-knit circle of friends led by Hema. The group is wary at first, but Gautham’s persistent pursuit pushes them to assist. As they probe Gayathri’s whereabouts, Hema begins to sense that something deeper is troubling him—perhaps a neurological condition that brings on amnesia and delusions. Her father, a psychiatrist known as Dr.Rajasekhar, steps in to assess the danger and weigh the options.

Six months earlier, Gautham’s research led him to a hill resort in Tamil Nadu, where he crossed paths with three Pondicherry men—Shanmugam, Soundar, and Prakash—who had been teasing Gayathri. The local girl sought refuge with Gautham whenever the trio harassed her. One night, after they get drunk, the mood turns violent: Balaji, Gautham’s friend, tries to intervene as the men molest Gayathri. In the struggle, Balaji sustains a knee injury from an axe, Gayathri faints, and Gautham is struck on the head with the blunt end of the weapon. In his memory, he fixates on a version where the three men murdered Gayathri and left him for dead. A crucial twist emerges later: Gayathri did not die—she merely collapsed.

The truth behind Gautham’s delusions becomes a central concern. [Dr.Rajasekhar] explains that if Gautham’s memories are restored, they could birth a different, potentially violent version of him—a dangerous possibility. The group decides to delay any action until Gautham’s mother arrives from Malaysia, hoping her presence might ease the turmoil. Until then, Hema selflessly cares for Gautham, and he grows fond of her, believing she might be the only person who can help him. In turn, Hema starts to care for him deeply and wonders if tenderness and support could coax him back to normalcy.

When Gautham’s mother finally arrives, the tides shift. His memory floods back, but so does a ruthless hunger for revenge. He turns on his mother and Hema, swearing to hunt down the three men who allegedly murdered Gayathri. The film shifts into a tense cat-and-mouse arc as Hema and Gautham’s mother endure his renewed aggression, while [Dr.Rajasekhar] crafts a clever plan to save him from himself.

The turning point comes when [Dr.Rajasekhar] and his allies manage to reconnect with the three men and uncover a startling truth: Gayathri is very much alive, and the only real sin was a drunken misjudgment that led to a brutal confrontation. The three men admit their guilt was a drunken mistake rather than murder, and Gautham seizes the chance to pursue justice rather than vengeance. He captures Prakash and Soundar, but the chase eventually leads him to Gayathri’s current home, where the truth finally begins to sink in.

Confronted with the reality that Gayathri survived, Gautham’s delusions melt away and he is cured. He offers apologies to his mother, to [Shanmugam] and to Hema for the torment he caused, and he reveals where the captives are being kept. Grateful for the effort that saved him, he thanks [Dr.Rajasekhar] and Hema for their roles in his recovery. As Hema watches him, she realizes this may be their last moment together, yet [Dr.Rajasekhar] signals his silent approval for Gautham to leave with his daughter, and the trio—Gautham, his mother, and Hema—set off together toward a possible new chapter.
