Annan Thambi is the story of dual brothers, Appu and Achu. Their father Ravunni, a ballet artist, separates them as a result of sibling rivalry, and Appu is distributed to stay with family in Pollachi. He grows as much as be a lovable thug who falls for Thenmozhy, whereas Achu marries Lakshmi. However quickly main misunderstandings created by their enemies crop up and the brothers are baying for one another's blood. Simply earlier than the climax, they arrive to the conclusion that others have been behind their enmity, so that they patch up their variations and tackle their foes.
