Plot

Padmanabhan master and his wife, Devaki, desperately await reuniting with Unni, their only son, who has been missing for many years. Ten-year-old Unni got lost in the crowd during a temple festival where he went with his neighbour, Panicker, popularly known as Poorappanikkar. Panicker too did not go back to the village as he decided to return only after finding Unni. Panicker's daughter Ammu also believes, like the Padmaabhan and Devaki, that her father will return one day with Unni. The master publishes a photo made by an artist based on assumptions about older Unni in the newspaper. He finds his son after years at Nagappattinam and brings him to the village. Soon, the villagers realises that Unni is abnormal and mentally challenged. He behaves like a small boy and creates all sorts of trouble for the villagers and his parents. His main hobby is to snatch mundu from people. This leads to a series of comical incidents in the village.
