Kathamuthu is a miserly schoolteacher, nicknamed "kuthirai muttai" [horse egg] because of his body. The combination of his strict teaching and his nickname has made Happy something of a local joke, with people calling him "kutti kuthirai muttai" [small horse egg]. The body-shaming that begins with Kathamuthu's nickname doesn't stay with him; it carries over to Happy and stretches across generations, being revisited so often that what starts as a running gag turns into something oddly mean-spirited. His romantic life had been greatly affected by his father, causing him to dislike his father more over time. Because Happy wanted an actual love life, without his father ruining it, he decided to go abroad.
When Happy is hired by an IT company in Bangalore and meets Kavya, the film finds its groove. Kavya actually likes him, but on the condition that his family formally approach hers. Happy fears this will prevent him from marrying Kavya and cause a breakup. Her father, Rajiv, is an NRI, and when he collides with Kathamuthu, when they finally meet at Rajiv and his wife's 25th anniversary, Kathamuthu arrives with his village [because that's tradition], and the culture clash between the city-bred father and the village traditionalist becomes the film's engine.
Rajiv tells his business partners that it ruined his honor and was like a circus. Kathamuthu hears this and soon meets Rajiv to show him all his wealth, to embarrass him, and prove him wrong. Near the end, they each demand an apology from each other in order for Kavya and Happy to marry, leading them to create many plans. In the end,[for his son] Kathamuthu apologizes to Rajiv. Soon after, Kavya's family and Happy board a flight abroad.
During the flight, Happy becomes emotional thinking about his father and his story, prompting them to go back. We then see a flashback to the opening scene, where Happy is about to go to New Delhi, but Kathamuthu sacrifices his ticket for someone else, preventing them from going. That someone is young Rajiv, going to a job interview, hiding in the train bathroom without a ticket. Rajiv realizes and finally apologizes to Kathamuthu. The story explores themes of fairness, as well as social levels and separations.
