How Das and co try to stay ahead of the cop and how he nabs them, and what happens forms the rest of the story.—Bhama Ravi

Dass specializes in small time kidnapping and has his own set of rules. The primary and most important among them is not to get involved with influential people.

Things get complicated when psychopathic cop Yog Japee is brought in to handle the investigation.—Anonymous

Friends Kesavan, Sekar, and Pagalavan meet Das, a middle-age man who does low-profile kidnappings for a living with his imaginary girlfriend Shalu. Since 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, the Das gang 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 honest politician. 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 Rs. 20 million. Das initially hesitates, but eventually agrees after being convinced by Kesavan, Sekar and Pagalavan.

The next day, the Das gang set out to kidnap Arumai but are astonished to see him be kidnapped by another group. They kidnap Arumai from the other kidnappers and discover that the first kidnapping was staged by Arumai himself to extort money from his father. Arumai manages to convince Das and his men to collude with him to obtain ransom money from his father. The group demands Rs. 20 million from the minister and receives the money.

An argument over splitting the cash arises between Arumai and the rest during which their van loses control and falls from a bridge. Arumai runs away with all the money. The minister seeks the assistance of encounter specialist Bramma, a ruthless policeman to hunt down the kidnappers. Arumai returns to his house and hides the money in his room. Das devices a plan to kidnap Arumai again to retrieve the money. They accidentally meet Arumai and successfully kidnap him again. Das lets Arumai go free, after making him promise that he should not tell anything about them to the police. Arumai also promises to return their share of the money. Bramma learns that Arumai staged his own kidnapping and uses this information to threaten Arumai into testifying against the Das gang.

Arumai perjures that the Das gang did not kidnap him, leading to their acquittal. Enraged, Bramma takes the gang to a remote location, brutally beats them in a dark room with the aid of NVG, and raises his department gun to kill them. Instead of shooting them with the officially issued gun, he goes out and retrieves from his police jeep an illegal homemade gun that he had seized from a crook. When he inserts it behind his back in his pants, the rusty gun misfires into Bramma's buttocks, allowing the Das gang to escape. Arumai's father breaks in and takes the money bag to the chief minister, who provided the ransom money. When he opens the bag, the minister is shocked to find it filled with newspapers instead of cash. Arumai had transferred the cash to another bag and gives the Das gang their share.

The chief minister calls Arumai to his office and asks him to stand as a candidate in the upcoming general elections in lieu of his father, who never brought much income to the party due to his refusal to be corrupt. The chief minister praises Arumai's shrewdness and believes that he can rake in a substantial income of Rs. 3 billion in five years for the party, as a young minister. Arumai wins the elections, becomes MLA, immediately gets a minister post, and appoints Sekar and Kesavan as his personal advisers, while Pagalavan becomes an actor. Das continues his kidnapping business with a new band of young men. They kidnap a woman who looks exactly like Shalu, belatedly realising that she is Shalini Gupta, a minister's daughter. Thus, Das has broken his first rule of kidnapping again.
