The film stars Arvind Swamy, Sukanya and Sivaranjini, while Goundamani, Senthil, Vijayakumar and Kovai Sarala play other supporting roles.

[2] ==Plot==' The story starts with a carefree young woman "Revathi" (played by Sukanya) stumbling upon a village called "Poombarai" (based in the Coimbatore area of TN).

The prospective family cancelled the proposal as they thought it was a bad omen that her saree was caught on fire.

One night, Chelladurai was coming back from somewhere while riding his bullock cart; visibly drunk, he passes by a home seeing a flame lit lamp on the window sill, as he desired to light up a cigarette.

Chelladurai is given 2 options, either tie the nuptial knot ("thalee") around Gayathri's neck and make her his wife, or face getting arrested and jail time for the crime he committed.

One evening, kuzhanthai was heading to Dr. Amma's home to drop off something and he ran into Chelladurai's friends; they were drinking alcohol and smoking.

She declined and decided to live her last days as a terminal patient, hence her leaving Chennai and traveling somewhere, eventually ending up in Poombarai.

As kuzhanthai finally wakes up, Chelladurai's goons won't allow him to leave and reveal to him the "story" they made up.

After beating down the goons, Periya Aathaa and Malli tell kuzhanthai to immediately see Dr. Amma as she's succumbing to her fate.

Kuzhanthai comes to Dr. Amma's home (while all the villagers rush towards there as well); he frantically calls her, but she doesn't answer.

After the overwhelming emotion of happiness, it turns to despair as Dr. Amma collapses and kuzhanthai catches her; she gives a final smile before passing away.
