The story follows (Dhanush), a well-settled family man living a peaceful life with his wife and daughter, Sathya. Their lives are upended when Sathya begins communicating with an unknown entity through a "spirit board" and exhibits disturbing behavior. Prabhu eventually discovers that his daughter is possessed by the spirit of a young boy seeking revenge. This leads Prabhu back to his dark past and his long-lost twin brother, Kathir (also played by Dhanush), a cold-blooded psychopath. Key Highlights
