Narthanga Saamy (Thambi Ramaiah) hails from a rich family but is addicted to horse betting, which makes him lose all his wealth. Kutty Maniyar (Umapathy Ramaiah) is the only son of Narthanga Samy, who roams around in the same village. Kuttimani loves his cousin Magizhampoo (Mrudula Murali) much against her father’s (Jayaprakash), wishes. Magizhampoo encourages Kuttimani to start a windmill business taking advantage of government subsidy. For the remaining equity part, she comes up with a plan of raising funds from the villagers and issue shares to them based on their investment. Kuttimani successfully raises Rs. 1 Crore from his friends and family members, but the money gets stolen by a cab driver named Chellakilli (Rajendran), which puts Kuttimani in trouble as everyone thinks that he has siphoned the money. Kuttimani initially suspects a local don Thanrasu (Pawan) to be the reason behind the theft but later understands that he has no connection. Finally, it is revealed that Magizhampoo’s father was behind the theft with plans of troubling Kuttimani so that he could not marry Magizhampoo. Knowing this, Magizhampoo gets furious and leaves her father, but Kuttimani and Narthanga Samy forgive her father, which leads to his transformation. Kuttimani sets up the windmill and also marries Magizhampoo.
