Rajini Murugan (Sivakarthikeyan) is an unemployed youth from Madurai who spends his days roaming around with his best friend Thotathree (Soori) and supplying food to his grandfather Ayyankalai (Rajkiran), a highly respected gentleman who has large properties of land. Ayyankalai wants to divide all his properties among his children and grandchildren, but except for Rajini Murugan and his father Malligarajan (G. Gnanasambandam), who is the headmaster of the local school, the rest of the family is settled abroad and never visit Madurai. 　　Meanwhile, following the advice of an astrologer (who claimed that Rajini Murugan will get married and be rich within three months), Rajini Murugan starts wooing his childhood sweetheart Karthika Devi (Keerthy Suresh). Karthika's father (Achyuth Kumar), an ardent fan of Rajinikanth, was the best friend of Malligarajan and had given Rajini Murugan his name when he was born, but fell out with Malligarajan and his family due to a misunderstanding 　　　involving Rajini Murugan and Karthika when they were children. Since then, Rajini Murugan and Karthika are not on speaking terms, and Karthika's father forbids any sort of contact between the two. Nevertheless, Rajini Murugan opens a tea stall outside Karthika's house to stay close to her and follows her day and night. Later, he and Thothathree start a real estate company. A gangster "Ezhrai" Mookan (Samuthirakani), whose only work is to extort ₹100,000 from businessmen, tries to swindle the same amount from Rajini Murugan, but fails and ends up paying ₹100,000 to him. 　　Ayyankalai, who is fed up with Rajini Murugan's antics, decides to immediately divide his properties so that Rajini Murugan can benefit from his share of the property. He fakes his death, which forces his children and grandchildren to come to Madurai. Mookan claims that he too is a grandson of Ayyankalai (through the son of Ayyankalai's first wife) and starts demanding his share of the property. This leads to confrontation between Rajini Murugan and Mookan and their feud is soon brought before the panchayat. The panchayat declares the verdict in favour of Ayyankalai and Rajini Murugan. Mookan, accepting defeat, receives ₹100,000 from Rajini Murugan as compensation. It is then revealed that Mookan staged the whole drama to get back his ₹100,000 from Rajini Murugan. Meanwhile, Karthika accepts Rajini Murugan's love and her father also begins to approve their relationship. 　　In the end, Ayyankalai reveals that he does have a grandson through his first wife's son. The grandson is revealed to be none other than Bosepandi from Varuthapadatha Valibar Sangam (Sivakarthikeyan). Bosepandi refuses to accept his share of his grandfather's property and advises him and his family not to sell the property but to convert it into a 5 star hotel and hand it over to Rajni Murugan . Ayyankalai and Rajini Murugan agree with him.
