“Sir 2024” is set in the village of Mangollai, where two opposing groups exist. On one side, there are figures like Colochi Saami and Saamikannu, who oppose education for the poor, keeping them oppressed. On the other side, individuals like Annadurai and Sivangaanam stand up for the rights of the underprivileged and fight against injustice, especially in the realm of education. The story explores the conflict between these forces and the struggle for a better future for the oppressed villagers.
