In the remote Indian village of Kadambam, an orphaned girl named Sevanthi becomes the living vessel for a powerful mountain goddess. Her world of quiet faith is shattered by the arrival of Parthiban, a cynical author determined to debunk her power through a cruel experiment. He introduces a charming philanthropist who is secretly a murderous predator, believing the goddess will be fooled by his pawn.
Instead, the goddess's omniscience unleashes a wave of betrayal, murder, and brutal, divine judgment that consumes the village. "Sevanthi" is a tragic story exploring the collision between ancient faith and modern arrogance.
