Easan (Dhanush) and his mother, along with other villagers, are victims of oppression. The local king imposes rules on them and also on the instruction from the Britishers. The people in the village are never allowed to step into the village temple which they built. One day, the arrival of his brother Sengolan (Shiva Rajkumar) in the village for the local festival, results in the death of his mother. He believes that it is better to serve the Britishers as he thinks that they give him respect. At the British camp, he gets rechristened as Miller. But, little does he realise that they are the bigger enemies.

His first assignment involves charging at a group of freedom fighters who are involved in a non-violent protest. He shivers and realises that he has blood in his hands. A dejected Miller decides to go back to his village, where he gets shooed away. His friends reveal that his brother Sengolan was amongst the freedom fighters. Miller is distraught and goes on to lead a nomadic life. Months later, he is discovered by a dacoit gang headed by Kannaya (Elango Kumaravel). How Miller realises the bigger purpose of his life and fights against oppression, forms the story.
