Nam Naadu (English: Our Country) is a 1969 Indian Tamil-language film starring M. G. Ramachandran (known also as MGR) and Jayalalitha. It is a remake of the 1969 Telugu film Kathanayakudu, which starred N. T. Rama Rao and Jayalalitha.
Dharmalingham (S. V. Ranga Rao), Aalavandar (S. A. Ashokan) and Punniyakodi (K. A. Thangavelu) are three VIPs in a township who have established themselves as noble citizens of the country but in reality are traitors who dare to do any type of crimes for money.
Durai (M.G.R) is an honest government office clerk who wants to be sincere for the nation and to help the poor and needy. In order to save the rights of the poor he fights with higher society people which is disliked by brother Muthaiya (T.K.Bhagavathi) who works for Dharmalingham and is an equally honest person as Durai. Though Muthaiya scolds Durai for his acts he is very affectionate to him and Durai is equally respectful and affectionate towards him and his family. Durai once picks a fight with Aalavandar in a shop — he insists on his standing in a queue like everyone else as there should be no special right for him over poor people. This creates tension between Aalavandar and Durai. Muthaiya worries that he will get into trouble because Aalavandar and Dharmalingham are good friends.
Durai meets a tender-coconut selling girl Ammu (alias Alamelu) (Jayalalitha) and gets attracted towards her nobility and honesty. Aalavandar takes revenge on Durai by making fake bribery complaint on him and because of which Durai loses his job. The enmity between Dharmalingham and Durai increases gradually because of which his brother shouts at him and ask him to get out of the house as Muthaiya believes Dharmalingham is honest and treat him like God. Ammu supports Durai and takes him to slum. Durai works for them and earn the love of slum people and people support him to contest and win in the municipal election. Durai takes action against the trio with his rights and enmity further increases. The trio plan and succeed to throw Durai away from the municipal office. Meanwhile, Muthaiya finds that Dharmalingham has looted a sum of Ten lakh Rupees which actually belong to the welfare of poor people. So he runs away with the money to save from them and he buries it in a place. But the trio catch him and shut him at a secret place when he refuse to open his mouth on the whereabouts of the money.
Now Durai plans to take revenge on them and to reveal themself and their crimes by their own mouth. Did Durai succeed in his mission and found the money and his brother forms the rest of the story.
