The story is written by A. C. Karunamurthy (Karnamurthy), dialogues by Radhakrishnan, and the film stars Rio Raj^[1] and Ramya Nambeesan. The music for the film is composed by Yuvan Shankar Raja while cinematography is handled by Rajasekar and editing is done by Sam RDX.

The film’s title was taken from a dialogue spoken by Vadivelu in Pokkiri (2007).

Two friends, Sembi and Raju, end up kidnapping a girl Aambal to know about the whereabouts of Raju's sister Radha, who had eloped with her boyfriend Bharath Raj. The film involves a bride-seeing event that spoofs the 1961 Tamil film Pasamalar; a driver Thilagam, who offers to give the protagonists a short ride but ends up travelling with them all the way to Kodaikanal; Arokkiyasaamy, a guy who shoots videos of men in a state of undress and blackmails them; Captain Kandasamy, the manager of a glamorous star, who is taken for a ride by the friends, who owe him money; and a monologue by Radha, which is amusing, even though it is representation of a young woman from a supposedly down market locality like Royapuram is troubling.
