The film begins with Kesavan (Udhai), after serving a prison sentence, traveling on a train back home to Palani and reminiscing about his past.

Aadhi (Prabha), Kesavan, Perumal (Sarvamathi), and Seenu (Padmakumar) were best friends living in Palani. Aadhi lived with his widow mother and worked in a small workshop, while Kesavan lived with his wealthy family and was jobless. One day, Kesavan scolded Aparanji (Unni Maya) at the hospital for not doing her job well, but he later felt guilty for insulting her and wanted to apologize. Thereafter, he came to know that Aparanji was a medical student who was on an educational trip in Palani, and she eventually befriended him. Aadhi, Perumal, and Seenu urged Kesavan to express his love. Kesavan then accommodated Aparanji and her college mates in his house. Kesavan was still afraid of expressing his love, but Aparanji finally came to know about it, and she gave him a love letter before going to her native town Tiruppur.

The four friends arrived in Pollachi to attend Kesavan's wedding, and Kesavan met Aparanji before the function. At a jewellery shop, Kesavan bought bangles for his lover with his friend Aadhi, and a police inspector (Mahanadi Shankar) suspected him of stealing his wife's bangles. The situation degenerated as Aadhi beat the police inspector up and Aparanji's father Subramani (Kadhal Dhandapani) had witnessed the fight. At the wedding function, Kesavan gifted Aparanji the bangles. Subramani, who has seen it, insulted Kesavan and challenged him to come to his hometown Tiruppur.

In Tiruppur, Aadhi challenged Subramani that Kesavan will marry Aparanji, but their first attempt failed as the gangster Thirthagiri (Tiruppur Selvaraj) intervened. Later, Subramani explained to the four friends that Thirthagiri wanted him to give his daughter to his brother, but Subramani refused. Subramani wanted Kesavan to save Aparanji from Thirthagiri by marrying her. Thereafter, the four friends and Aparanji were arrested by the vengeful police inspector, and he took them to Thirthagiri's factory. The five managed to escape from Thirthagiri's henchmen. After getting separated, the friends who had defeated Thirthagiri's henchmen got together, and they had a brutal fight with Thirthagiri. When Thirthagiri tried to kill Kesavan with a machete, Aadhi sacrificed his life and died. A vengeful Kesavan then killed Thirthagiri.

Back to the present, Kesavan arrives in Palani and meets Aparanji, Perumal, and Seenu.

The soundtrack was composed by C. D. Shaju. The soundtrack features 5 tracks written by Palani Bharathi and M. C. Duraisamy.

A critic said, "There is a sense of déjà-vu throughout the film reminding you of many similar ones [..] What the director has managed to convey is the friendship factor, especially the deep bonding between Adhi and Keshavan. Rising heroes Prabha and Udhai essay their characters with total involvement and conviction and play a major part in bringing out this friendship factor effectively on-screen".^[8]
