Karthik and his friends plan a trip to Kodaikanal where they meet a doctor and his 12-year-old daughter Shalini. While sight-seeing, they get in trouble with a gang that grows cannabis illegally. The next morning, Karthik is found dead and Shalini is missing.

The movie is a tribute to the film actor Rajinikanth.

An obese man, living in the slums of Chennai, comes across a series of situations that change his perception towards life and love.

College goer Karunakaran (Arulnidhi) finds it difficult to adjust with the society that he lives. As a result, he is unable to control his anger and ends up with trouble. His unpredictable behavior becomes a constant worry for his mother (Sujatha Sivakumar) and brother. A series of incidents force him to leave his hometown Madurai and end up in Chennai. Despite scoring high marks in school, he joins a local arts college in the city and stays in a hostel, where trouble begins. Meanwhile, while traveling from Bangalore to Chennai, Assistant Commissioner Marimuthu (John Vijay), Inspector Rajendran (Madhusudhan Rao), Sub-Inspector Selvam (Balakrishnan), and Sgt/Head Constable Perumalsamy (Krishnamurthy) witness a car accident. When they are about to take the victim (son of a Bangalore-based business tycoon) to a nearby hospital, they come across a huge stash of cash. The policemen kill the half-dead victim and flee to Chennai with the money. The sincere police officer Palaniammal (Uma Riyaz Khan) takes up this case. A cluster of lies, ego clash at the hostel, and family’s ignorance brings Karunakaran into this crime plot. The rest is a racy rollercoaster ride that forms the climax.
