The film begins with a stunning action sequence on a moving train, where Alex Pandian (Karthi) and Divya (Anushka Shetty) are attempting an escape from the goons. Afterwards, a crazy comic sequence unfolds with Alex uninvitingly lands up at Kaalayan's (Santhanam) house, for a temporary stay while Divya recovers at a treatment center. Being a small time crook, he is hired by an NRI Businessman Alvin Martin (Milind Soman), Dr GKM (Suman) and a Godman (Mahadevan) to kidnap the Chief Minister's (Visu) daughter. In a desperate attempt to get the Chief Minister's approval for the shipment of banned drugs in Indian territory, which would in turn, earn a huge sum of money. Alex, unaware of their intentions, agrees to abduct Divya but his reckless change of heart puts them in trouble. What happens next forms the rest of the film. (CBFC U/DIL/1/1/2013-CHE)
