"Kannappan is posted to Perumalpuram as the new schoolteacher. The village lies in the black soil region of Tamil Nadu where the river Tamirabarani flows. He’s an outsider in this village with Veerayyan, a local farmer, as his only guide and friend.
Once settled in his role, Kannappan observes the everyday brutality faced by the farmers at the hands of the sadistic, all-powerful landlord-the Master. Child marriage is common in the village and so is the appalling practice of marrying young lads to older women who then serve as their father-in-law’s consort. Through his gentle yet probing conversations with the villagers, Kannappan tries his best to show the villagers a better way of life. The farmers who had begun protesting the excesses meted out to them by the upper-caste landlord soon find an ally in Kannappan. The schoolteacher’s sympathies for their cause bolster their waning spirits and replenishes their resolve to fight back."
