Anbarasan is a secondary school social science teacher in Pondicherry. He is loved by his students as he was an irresponsible and carefree teacher who didn't prioritize his students' studies. This always got the school principal disappointed. Anbu came from a rich and successful family, his father is Ulaganathan. In his village, where caste and religion are still used, Ulaganathan completely disregarded this and encouraged the villagers to stop practicing these. Ulaganathan is embarrassed as his daughter eloped and married her cousin (Ulaganathan didn't approve of inter-family marriage) without his consent. He hopes that Anbu won't follow these steps and makes him sign a document.

Meanwhile, Jessica, a British woman born and raised in India finds a job as an English teacher in the same school in which Anbu works. Anbu develops a crush on her and tries to show off whenever around her. However, her father Williams wants to move out of their house and return to England. His ownership of the land is challenged by Bhoopathy. Bhoopathy discriminates against Williams stating he is not an Indian in an attempt to take over his property. Jessica's student Mahesh scores a 6/25. The principal is disappointed in Jessica, so Anbu decided to tutor Mahesh. Mahesh's grade improves to 18/25, Jessica notices this and develops a liking for Anbu. Anbu confesses his love, at first she is doubtful, but soon reciprocates these feelings. Williams takes his case to the police, but his case is withdrawn. Anbu tells his parents about Jessica, and Jessica comes to meet them. She states she is from the French Colony, of Cambridge. Ulaganathan finds her a nice woman, and Anbu and Jessica are happy.

Anbu starts supporting Williams's case, by telling Bhoopathy to stop, but Williams still doesn't like Anbu (believing he is like all Indians and just discriminative). Ulaganathan had believed the entire time Jessica was French, but when he realized she was actually British, he disapproved of Anbu and Jessica's relationship. This was mainly because Ulaganthan's grandfather, the respected Veluchamy, was killed by the British. At a pub, Anbu and Jessica celebrate Anbu's friend's birthday. They inadvertently start celebrating when England defeats India in a cricket match, Boopathy believes they are celebrating India's defeat. A fight occurs, and Anbu hits Boopathy's head, which starts bleeding. Williams sees this and realizes Anbu is different and actually a good man. He invites him for dinner and Anbu learns that his family had lived in India for 50 years. Jessica's grandmother had fled to India when World War II occurred.

Every year, Ulaganthan is given the honor to raise the Indian flag every August 15 (India's Independence Day). However, this year he is not allowed, because of his son's actions of hitting Boopathy and supporting a British. Ulaganthan believes that Boopathy actually owned the land (he didn't know the truth). Ulaganathan is angry and alongside the villagers wait at the doorstep of Williams's house. There he confronted Williams. Williams wants to talk with Ulaganthan in private, when he tried to guide Ulaganathan into his house, the villagers were pulling on him and Ulaganthan fell into the mud. Though it was the villagers' fault, the villagers spread rumors that Williams pushed him into the mud. This soon becomes a revolt and the villagers assembled in front of Williams's house and threw rocks into his house,

Williams had no choice but to take his entire family back to England. Anbu and his friends start fighting the protesting villagers, but the police are called and he's taken alongside his friends. He is exiled from his village for a week. Jessica goes to Ulaganthan's house and tells him the truth, she also on behalf of the Britishers who ruled India apologized for ruling them. Ulaganathan and his wife feel pity for Jessica and her family. Before Anbu is kicked out, he makes a speech. He eventually says patriotism or humanity. The villagers realize their mistake and let Anbu back in. Anbu catches up to Williams, Jessica, and their grandmother who had been pulled over. They all apologize and Ulaganthan wholeheartedly welcomes them back into the village, promising to treat them with respect and also accepting Anbu and Jessica's love.
