Kalyanaraman

Kalyanam, Chinnadurai's naive son, dotes on Shenbagam, a worker on the estate. He pursues her despite his childish ways and the social gap between them. His affection sets the stage for conflict when the estate's future hangs in the balance.

The estate's manager schemes to seize Chinnadurai's wealth and property. He teams with Perumal and Samipillai, driven by greed. To solidify his plan, a goon is hired to silence Chinnadurai.

On his deathbed, Chinnadurai reveals that he abandoned his first wife Rajalakshmi and Kalyanam's twin brother Raman in Madras. He urges Kalyanam to travel there and protect the family's future. The revelation reframes the stakes for everyone involved.

Kalyanam shares his father's Madras plan with Samipillai, hoping for support. Samipillai, seeing an opportunity, leaks the information to the manager. With the betrayal, their scheme gains a vital foothold.

Samipillai hires actors Kittu and Rangamani to pose as Raman and Rajalakshmi, creating a forged path to claim the estate. The impostors are fed stories to convince others of the twins' return. The deception threatens to pull the family into ruin.

Kalyanam overhears the gang gloating about their deceit and rushes to inform the police. The warning comes too late, and the gang traps him before help can arrive. His attempt to thwart the plan underscores his devotion to Shenbagam and the truth.

The gang corners Kalyanam and murders him, ending his bid for justice. Shenbagam watches the brutal killing and descends into mental instability. The estate is left reeling as the conspiracy tightens its grip.

The gang silences the other witness by cutting out Kuppu's tongue, preventing him from testifying. The silence compounds the danger around the estate and delays legal action. Yet hope remains in the shadows of the conspiracy.

Now a ghost, Kalyanam travels to Madras to locate Raman and their mother Rajalakshmi. His spirit persists as a beacon, guiding the truth back to the living. The journey shifts the battle from the estate to the city.

In Madras, Raman discovers that he has a twin brother and that deceit led to his family’s ruin. He resolves to seek revenge against the impostors and restore his family’s honor. The revelation sets the stage for a counterstrike from beyond the grave.

Raman arrives at the estate and exposes Rangamani and Kittu as frauds. He even adopts the guise of Kalyanam's ghost to terrify Samipillai into confessing. The impostors crumble under the weight of the truth and fear.

With Kalyanam's invisible aid, Raman helps Shenbagam regain her sanity. He also teaches Kuppu to read and write so he can testify, turning the boy into a witness against the conspirators. The estate begins to breathe again as education and truth take root.

The manager and his gang are arrested thanks to Kuppu's testimony. The legal system closes in as the truth is finally acknowledged. Justice arrives at last for the vulnerable.

Raman and Shenbagam marry, bringing peace to the estate and sealing the victory over deceit. The family reconciles, and the liminal world of ghosts fades as happiness returns. A new, hopeful chapter begins for everyone involved.
