A commercial potboiler with a twist, the film begins with Saidhai Satya (Sundar) who is a professional hit man and does anything for money. His main mentor happens to be the dreaded gangster Annachi (C M Kumar) and while Satya poses as a businessman in front of the public he is actually a thug. Annachi has a close ally in the form of an ex-minister (Manivannan) who is evil to the core. Gradually, Satya becomes arrogant and as luck would have it he and his constable friend Kandaswamy (Vivek) get drunk in their car, cause traffic jam and a case is filed against them by the honest lawyer Udayamurthy (Vijaykumar). Satya wants to hit back and in one such instance, he is successful but then the accident leads to the death of the lawyer. Interestingly, Udayamurthy gives a blessing to Satya which really strikes the heart of Satya and due to the case filed, he is ordered by the court to serve term in the Gandhi museum. There, Satya meets a former freedom fighter (Nazer) and gets truly influenced by him. Satya is a changed man by the time he is out and unable to fight his guilt, he decides to uncover the truth behind Udayamurthy’s killing. He parts ways with Annachi and gets on to his mission. Meanwhile, he also has a love angle with the beautiful Meena (Anjali). What happens in the end forms the rest of the story.
