Plot

Padmanabhan and his wife Devaki are waiting for Unni, their only son who has been missing for many years. Ten-year-old Unni gets lost in the crowd during a temple festival where he went with his neighbour, Panikkar, popularly known as Poorappanikkar. Panikkar too did not go back to the village as he decided to return only after finding Unni. Ammu is Panikkar's daughter who also believes, like the master and his wife, that her father will return one day with Unni. The master publishes a photo made by an artist based on assumptions of older Unni in the newspaper. He finds his son after years at Nagappattinam and brings him to the village.
