Friends Mani and Ramani are B.Com and SSLC graduates respectively. They have difficulties finding a job suited to their qualification. Even if they find a job, they are unable to sustain in their job for long due to their attitude. Due to their innocence, Mani and Ramani are often fooled by people. One man sells them a cow saying it will give them many litres of milk per day, but the cow ends up hardly giving them any milk. After such failed endeavours, they meet an agent, who promises them to take them to Dubai and give them a job there. They give all their money to the agent, and he tells them to get on a boat. But they are fooled because the boat goes to Kerala instead. In Kerala, a drug smuggling gang mistakes them for CID officers due to some hilarious misconceptions and funny incidents. How Mani and Ramani survive in Kerala, and at the same time, how they unintentionally cause the smuggling gang to get caught by the police, forms the rest of the story.

The soundtrack consist of four songs composed by Chandrabose, with lyrics written by Vairamuthu. The song "Vaisakha Sandhye" from Nadodikattu was retained in Tamil as "Poo Poothathu".^[6][7]

The Indian Express wrote, "The comedy line sometimes falters as it does when [Pandiarajan] keeps harping to the point of nausea on his educational attainment and his friend's lack of it".^[8]
