Arjun Ramakrishnan (Vishal) comes to Chennai to woo a psychology student Divya (Tamannaah), on whom he has a crush. With the help of Deva (Soori), a local incompetent don, he succeeds in winning her heart. Divya's elder brother is Tamizhselvan (Jagapathi Babu), the honest and sincere DCP of Chennai. He approves the relationship between Arjun and his sister and soon their wedding is fixed. One day, Tamizhselvan is kidnapped by some goons in retaliation for his thwarting of a black money scam six months ago. Arjun rescues Tamizhselvan and takes him home, only to reveal that he is actually a CBI officer who had discovered ₹250 crore stashed in Tamizhselvan's house as black money. ₹300 crore had been seized during the black money raid, but it was publicly announced that only ₹50 crore had been seized. Arjun takes away all the money, but does not arrest Tamizhselvan due to his public reputation, instead telling him to personally surrender later that day.

However, Tamizhselvan soon finds out that Arjun is not a CBI officer, but is a criminal who had recently been released from prison. He pursues Arjun with the aim of getting back the money. During the chase, he opens fire on Arjun's SUV, causing Arjun to lose control and meet with an accident, losing consciousness. Arjun wakes up in a hospital, having lost his memory. Tamizhselvan keeps Arjun in custody in a house, where a psychiatrist Dr. Boothri (Vadivelu) is assigned to restore Arjun's memory so that he can reveal where he has kept the money. But, unknown to anyone, Arjun had not lost his memory; he is only pretending as part of his mission to retrieve black money. At night, he sneaks out of the house and steals the black money of an Union Minister (Jayaprakash), converting it to white money with the help of a hawala trader. However, Tamizhselvan and the minister soon find out that Arjun had not lost his memory and has stolen more black money. Arjun, confronted by Tamizhselvan and the minister, reveals his motive for stealing the black money.
