Friends Kesavan, Sekar, and Pagalavan meet Das, a middle-age man who does low-profile kidnappings for a living with his imaginary girlfriend Shalu. Because they are broke, the trio decides to become his assistants. Das follows five rules of kidnapping (which he spells and writes as "kednaping"), the first of which is to avoid kidnapping people from political backgrounds. One day, they kidnap a boy and successfully obtain ransom money from his father Nambikkai Kannan. Nambikkai's contractor brother has been arrested for attempted bribery by State Minister Gnanodayam, a disciplined politician who plays by the book. Impressed with Das's kidnapping skills, Nambikkai asks him to kidnap Gnanodayam's son Arumai Pragasam as revenge and offers to pay Das up to 20 million.
