Assistant Commissioner of Police Shivakumar Indian Police Service (Raghava Lawrence) is a corrupt police officer who gets HIMSELF transferred to Chennai and misuses his power to gain money in unorthodox methods. During this process, he encourages an Member of Parliament named GK (Ashutosh Rana), who has become a headache to Kirubakaran (Sathyaraj), the Police Commissioner of Chennai. Shiva happens to be Kiruba's son, who is angry on the latter as his supposed negligence killed his mother (Sukanya (actress)) and just-born sister, though Kiruba actually left his wife in the hospital to save several families in a riot. Unaware of this, Shiva left Kiruba, joined an orphanage, and became an IPS officer to seek revenge on him.
