Ramalingam believes in formless God more than anything else in this world and worships all forms of Gods right down to newspaper clippings. He works in a bank where he is constantly mocked. Even his wife looks down upon this habit of his.
He is once called by God, which he initially considers a prank, who tells him that he has to inform people about the various things about to happen in the future. He starts believing that the person he spoke to, in form of Sivaji Ganesan, is God when he is summoned to 18th floor of a 7th floor building through a lift when he is unable to replicate.
Ramalingam starts his task of telling people, but no one believes him in the beginning. However, his "predictions" of train accident, among others, start to happen in real time. Slowly when what he says starts occurring people term him a powerful monk and start coming to him. God takes several other famous actor forms and keeps hinting the world through Ramalingam. One day, God tells Ramalingam that his son is going to die. The tables turn and Ramalingam starts cursing God though he still keeps his faith. In the end, he is arrested as a terrorist for pointing out a train accident before it happened, something one cannot know without inside knowledge. God appears in court which the judge mocks. God disappears in front of all to show he is God and Ramalingam is not insane. God gives Ramalingam his son back saying this is why God no longer interferes in human affairs.
