Naadodigal

The film revolves around Karuna, alias Karunakaran Natraj (Sasikumar), Paandi (Bharani), and Chandran (Vijay Vasanth). The trio eat, sleep, and party together in Rajapalayam. They also have their individual ambitions in life. Karuna is a history graduate and a university rank holder, although his father Natraj (L. Raja) sometimes ridicules the value of his degree, B.A. History, as many colleges do not even offer such a course anymore. Despite this, his father, mother, grandmother, and sister love him dearly and view him as a source of inspiration for their family. Karuna is in love with the daughter of a distant relative, Nallammal (Ananya). He is madly pursuing a government job because Nallamal's father will agree to the marriage only if he obtains one. Paandi (who is often discriminated at home by his father to appease Pandi's step-mother,) is desperate to go abroad and get rich, while Chandran, who is working as a software teacher, is committed to start a computer center and is in love with Pavithra (Abhinaya), Karuna's sister. Chandran's father is a widowed army veteran and is all decent to help his son's love.

All goes well until Saravanan (Ranga), Karuna's childhood friend from Kaniyakumari, arrives in town. The son of a former MP and a prominent politician, he is in love with Prabha (Shanthini Devi), the daughter of a rich bigwig Pazhanivelraman (Jayaprakash) in Namakkal. Shocked by Saravanan's suicide attempt due to love failure, the trio promise to help him out and unite the two lovers. They set out to Namakkal where they enlist the help of their friend Maariyappan (Ganja Karuppu).

The trio manage to help the couple get married by abducting the girl while she is visiting a temple with her family. In ensuing fracas between the two families, Karuna gets scarred near one of his eyes; Paandi is hit on the ear by a pipe, thereby becoming deaf; and Chandran loses his leg due to an injury by falling under a passing truck. Palanivelraman, on realizing who aided his ward escape, sends his goons to attack Karuna's family. It ends with Karunakaran's grandmother being killed.

During the funeral, the family members have a fight due to Karuna being arrested, hence hindering his ambition of obtaining a government job. Nallammal's father insults Karuna, angering Natraj and Karuna's mother. Natraj angrily tells him that anything Karuna does will always be correct and that he is proud of Karuna for the man he is. Nallammal's father questions his daughter's loyalty, as she wants to marry Karuna as well, and she breaks down, and he realizes she is still hoping for Karuna to be her husband. Nallammal's father angrily leaves and says she can have Karuna, but after he is dead, hanging himself from a fan in their house in front of Nallammal and her mother, before being let down by the help of their neighbors. This results in Karuna's fiancé Nallammal being coaxed by her parents to give up on him, and marry a better suitor. Nallammal sadly follows her father's orders to stay away from Karunakaran and that should she ever be seen speaking to him, she would never see her father alive again.

The three friends end up being put in jail and getting entangled in a kidnapping case. However, they are released as time goes by. After slowly experiencing hell upon return to their native town, they begin working alongside a local wedding food caterer and eventually begin to adjust to their new lifestyle.

Pandi leaves his house and even though his father insults him publicly, Pandi cannot hear anything being said. After being hit by his father, Pandi tells him that he always loved him, but he couldn't be the son his father wanted to be. Pandi's father realizes his selfishness and feels saddened at this and tries to call Pandi back, but Pandi cannot hear him, and simply walks away despite his father's cries to come back home.

Chandran's father laments for his son losing his leg, but tells him to stay strong as he can still come up in life. When Pavithra walks in to see him, she sobs at his lost leg and inability to walk, and Chandran's father goes out of everyone's sight and breaks down at his son's fate, but still stands by his son to succeed in life.

Karuna returns home and is traumatized, as he lost his beloved grandmother, and the entire family laments for his pain and efforts. His father tells him, whatever he did was fine, but he has to give up on Nallammal due to her father's behavior at the funeral. Karuna, heartbroken, agrees and decides to work as the caterer's aid, helping with cooking and serving. His family, albeit supportive, lament for him.

One day, Karuna's fiancé's wedding is announced, and they are told to serve food there. Karuna is shattered, and Pandi goes to the fiancé's house and wreaks havoc with her father, reprimanding the entire family, telling them that no man on the earth is as good as Karuna. He questions Nallammal about her loyalties and she looks at her father. When Nallammal's father is silent during Pandi's rage, he realizes that Nallammal's father threatened to hang himself, hence the reason why Nallammal stopped talking to Karunakaran. He threatens to kill the father, saying that him being alive is not beneficial to anyone. Pandi nearly succeeds, until Karuna rushes to stop him, and reasons with him. Karuna slowly becomes depressed afterwards, as the girl he loved so much is going to marry another man due to her father's adamancy.

Pavithra's love with Chandran is caught by her parents, for which she is shouted at and hit by them, but Karuna stops them and advises them to allow her to marry Chandran, since he was unable to marry the girl of his choice. Despite some hesitation, both parents relent, making everyone happy. Pandi has a hearing aid implanted in his ear and can hear again, while Chandran uses a prosthetic leg to be able to walk again, albeit with Pavithra's and his father's support. Life slowly begins looking up for the trio after a very long time, with Karuna also letting go of his past love for Nallammaal.

Eventually, the case filed upon the trio is withdrawn, and they find out through Karuna's uncle who helped them with the star-crossed lovers that they had managed to unite. Such great personal and emotional losses have gone their separate ways, having grown bored of each other and sex. They realize the battle they fought did not serve any purpose. They also learn that Saravana and his ex-wife are planning for their respective second marriages.Furious, the trio go to Kaniyakumari, to talk sense to Saravana. All of them are ridiculed and rebuffed without remorse. They gather again and prepare to kidnap Saravana and the girl. Pandi and Chandran go to Namakkal and kidnap her, while Karuna goes back and kidnaps Saravana. The trio bring them to a desolated forest area and whip them black and blue. Karuna then tells them to reconsider their live together, so that their sacrifices don't go in vain.

The trio then go to a tea stall, where they overhear another man trying to group people to help his friend's love and these guys volunteer.
