There prevails a norm that the heirs of Lingeswaran who constructed the temple are only eligible to do the re-opening. So Viawanath's grand daughter Anushka goes in search of the builder's grandson Lingaa and that is Superstar Rajini.
In Chennai, Rajini with his friends Santhanam and Karuna are caught by police for robbing and are imprisoned. Anushka gets them released, narrates the past and requests Lingaa to come to the village and do the needful but Rajini refuses.
Then he steals a jewellery worth 1.5 crores with his friends and gives it to Madanbob. Anushka gets Madanbob arrested. Fearing of getting into trouble, Rajini accepts to go to Solaiyur with her. There Viswanath reveals that the idol in the temple is made out of emerald and it should be safeguarded by Rajini. But when Rajini goes to the temple with the plan to loot the idol, the village people surround the temple thinking that some culprit is inside.
In order to escape from them, Rajini opens the temple and worships the God. Then he comes to know about the glories of his grandfather Lingeswaran. Feeling bad about his self, he decides to leave the village. Chairman Viswanath then informs Rajini about the murder of Ponvannan and the M.P's plan that will put the temple and the dam in danger. He says that Rajini should save the people and the village from disaster. The rest of the story narrates how Rajini fulfills the request.
The introduction song starts in an excellent way. As usual, Rajini satisfies his fans by taking the onus on his shoulders. By his unique style and dialogue delivery, he impresses the viewers in the dual roles.
Anushka has done full justice to her part. Sonakshi Sinha has also given an impressive performance. Santhanam can be appreciated for the comedy.
Ace director K.S.Ravikumar has done the story, screenplay, dialogue and direction according to the expectation of the fans in a short period of six months and has proved himself. He has given a feast to the audience with lot of interesting characters, brisk storyline and expansive song sequences.
Randy (a) Ratnavelu's camera visualizes the mega dam before the viewers in a grand manner. The difference between the two periods is shown clearly by him. AR Rahman's music is excellent and enhances the beauty of the script.
