Saidai Sathya is a mechanic who has little respect for the law. He parks his car in the middle of the road and creates trouble for other vehicles. A traffic policeman named Kandasamy ignores that violation because he is a close friend of Sathya. A social activist and lawyer, Udhayamoorthy, drags both of them to court for obstructing traffic and causing a nuisance. The court finds them guilty, but instead of sentencing them, the court sends them to the
Madurai Gandhi Museum for help, where they meet a college student named Meenakshi. After Sathya is discharged, he starts a job as a henchman. VBR, a former minister, sends Sathya to steal a confidential file containing vital evidence on the death of collector Leelavathi at Udayamoorthy's place. While Sathya is stealing the file, Udayamoorthy dies by being pierced by a steel rod. While dying, Udayamoorthy blesses Sathya by saying "Vazhga Valamudan" (Long Live). These last words haunt Sathya, and filled with remorse, he vows to carry on Udayamoorthy's good work. Sathya gathers evidence to expose VBR, whom he discovers is Leelavathi's murderer. VBR's goons burn the documents to destroy the evidence. Sathya continues with his task of exposing VBR and adopts
Gandhian principles of nonviolence and peace (
satyagraha). Ezhumalai, an
Assistant Commissioner of Police, vows to avenge the death of his brother Udhayamoorthy. He thinks that Sathya killed him, although he later finds out that he did not. Sathya sits near the Gandhi statue and follows his examples of nonviolence, confident that VBR will be arrested. As he is sitting, many citizens and police order him to leave, though he does not budge. They later follow suit and sit in front of the statue. At one point, however, Sathya gets shot. Meanwhile, many people start to protest against VBR. After getting beat up and almost left for dead, VBR surrenders himself to the police. The film ends with Sathya surviving his shot and getting the justice. == Cast ==
