After a decade of research, the scientist Vaseegaran creates a sophisticated android robot with the help of his assistants, Siva and Ravi, to commission it into the Indian Army. He introduces the robot, named Chitti, at a robotics conference in Chennai. Chitti helps Sana, Vaseegaran’s medical student girlfriend, cheat in her examination, then saves her from being assaulted by a group of thugs. Vaseegaran’s mentor, Professor Bohra, is secretly engaged in a project to create similar android robots for a terrorist organisation, but has so far been unsuccessful.
Vaseegaran prepares Chitti for an evaluation by the Artificial Intelligence Research and Development (AIRD) Institute, which is headed by Bohra. During the evaluation, Chitti attempts to stab Vaseegaran at Bohra’s command, which convinces the evaluation committee that the robot is a liability and cannot be used for military purposes. Vaseegaran’s effort to prove Bohra wrong fails when he deploys Chitti to rescue people from a burning building.

A dam in the village of Solaiyur, which is the lifeline of that village is under assessment for structural integrity by the Public Works Department. The dam inspector (Ponvannan) assesses that the dam is still strong 75 years after it was built. Later that evening, he is hanged to death by the corrupt local MP Nagabhushan (Jagapathi Babu), who wants the dam destroyed for his own benefit. The dying dam inspector throws a pen drive containing details about the proposed plan to destroy the dam into an abandoned Shiva temple near the dam and warns the village head Karunakara (K. Viswanath) that the temple has to be opened as soon as possible, after which he passes away. Karunakara and the villagers are of the opinion that the temple can only be opened by the descendant of Raja Lingeswaran (Rajnikanth), who built the dam as well as the Shiva temple. Lakshmi (Anushka Shetty), the granddaughter of Karunakara and a television journalist, goes on a search to find the Raja’s descendant. She soon manages to find the descendant, whose name is Lingeswaran aka Lingaa (Rajnikanth). Lingaa is the grandson of Raja Lingeswaran, but is a petty thief with his family having now fallen on hard times. He holds a grudge against his grandfather, feeling that he had brought down his family into poverty by squandering all his wealth and hence refuses to go with Lakshmi to Solaiyur. However, Lakshmi implicates Lingaa in a robbery, as a result of which the police pursue Lingaa. Lingaa is forced to accept Lakshmi’s invitation to avoid getting caught and travels with her to Solaiyur.

The film begins with Murugesan (Bharath) limping sorrowfully from the Central Jail, Palayamkottai, in a scruffy beard and glasses. He has been imprisoned for 17 years. The film flashes back to 1989, where Murugesan is an unruly youngster in Sivasaila. He is the son of flower sellers (Rajesh and Yuvasri), with Thapaal Thangavelu (Vadivelu), who provides as much laughter as the posts he delivers. Life is a long, sunny adventure for Murugesan, who beats people up, sells his grandfather’s land, runs over rooftops, and incurs so much of his father’s wrath that he is prophesied to meet a horrible end. Not that this gloomy prospect affects him – he continues on his own sweet way until he runs into Parijatham (Poonam Bajwa), a demure, fair-complexioned, striking Iyer girl, the daughter of Panjami Iyer (Y. G. Mahendran) and the younger sister of Gayathri (Simran). In the meantime, the village’s bigwig Periyavar (Sampath Raj), who is magnanimous in public and a tyrant at home, casts his eyes on Parijatham. He places his pawns carefully and is afraid of being found out. Parijatham is trapped, and Periyavar starts removing her dresses. He and Murugesan come close to breaking each other’s bones many times, but the situations defuse themselves in a perfectly natural fashion. Several twists in the tale occur in a quick fashion, and Murugesan and Parijatham are bound in a net from which, seemingly, there is no escape.
