Kochukunju, Prithviraj Sukumaran, is the youngest, spoiled son of the Vadakkanveettil Tharavadu in Taliparambu, Kannur. He carries the weight of a complicated family history and a father whose identity has threaded through lies and revelations. His mother Katrina, Ambika, is the family’s youngest daughter, and she bore Kochukunju with a wandering stage artist named David Saikumar. Though the world believed David to be dead, the truth later surfaces: Kochukunju’s father is alive, and he has kept an eye on his son from the shadows, waiting for the right moment to reveal himself.
Within the sprawling estate, Kochukunju is largely hated by the clan, save for two people who see something redeeming in him. His younger uncle and his cousin-fiancée Helen, Sheela Kaur, know that his apparent honesty and stubborn sense of right and wrong could be a shield against the family’s greed. The family’s tension centers on the Vadakkanveettil property, which everyone else is eager to parcel out for personal gain. Nelson, the cousin who dabbles in crime, believes Kochukunju is a stumbling block, and the potential for conflict grows as the estate’s fortunes hang in the balance.
In a hotel brawl that becomes a turning point, Nelson’s opponent ends up dead by accident, and Kochukunju becomes the focal point of trouble. Kochukunju’s friend and manager, Nandan, Sudheesh, steps in to shield him and takes the blame in court, a move that cements Kochukunju’s stubborn resolve to stand by those who have shown him loyalty. This act forces the family to confront more than just money; it exposes the chasm between appearances and the truth lying beneath them. The courtroom battles reveal that Kochukunju is not the empty vessel many in the family assume him to be; Katrina, moved by events and the weight of years, begins to see the changes in her son and begins to question the path the clan intends to force upon him.
As the family’s schemes unfold, Kochukunju’s true loyalties surface. He refuses rehabilitation at the tainted de-addiction center; his stubborn pride, tempered by the quiet guidance of his mother and Helen, pushes him toward a self-imposed discipline. In prison, Nandan is beaten and hospitalized, yet Kochukunju’s restraint helps prevent further violence, underscoring the strength of the bonds that have begun to form between them. The tale takes a dramatic turn when Helen visits a windmill area and learns that the land is controlled by a single powerful owner. There, she encounters Kochukunju, who is ultimately revealed to be that very owner, a realization that reframes the entire narrative. The flashback reveals how Kochukunju met his father and promised never to fail his family in the face of contempt.
Kochukunju’s journey takes him to Dubai, where he works in a fish market and befriends Nandan. There, he saves Hafees Ali Ibrahim, Pithamagan Mahadevan, a do-gooder who commands respect in the local community. Ibrahim trusts Kochukunju more than his own sons, and leases wealth to him through their mutual ally, the lawyer Anand Sharma, P. Vasu. When Ibrahim’s three sons murder their father and attempt to pin the crime on Kochukunju, the court clears him, and the sons are jailed. Kochukunju’s sense of justice remains steeped in a desire to protect the vulnerable, especially Nandan, who stands by his side through the hardest moments.
The brothers’ release from prison deepens the conflict, and Kochukunju and Nandan feel the sting of betrayal as the brothers attempt to seize their inheritance. Kochukunju heads back to Dubai to confront them, a mission that culminates in fateful battles that leave the trespassers defeated and the truth about ownership finally acknowledged. The true owner remains the very man who had guided Kochukunju from the shadows, David, Saikumar who reveals that Kochukunju is the rightful owner of the family wealth. Katrina’s brothers had even plotted to kill him, but the revelation changes everything, shifting the power balance back to Kochukunju.
Back in Kerala, a stranger’s purchase of some land sets the stage for the climactic revelation. The real owner steps forward, and the family discovers that Kochukunju is the legitimate heir who has acted with restraint and courage all along. David returns to confirm the truth, and the family’s wounds begin to heal as a new unity forms. The moment of truth arrives in a room where Kochukunju’s photograph sits beside a lit candle. His mother’s gentle yet firm rebuke—an embrace of forgiveness and honesty—brings the family together. With David’s blessing and Katrina’s permission, the candle is blown out, signaling a peace long sought but hard-won. The family, united at last, includes Kochukunju, Katrina, his mother, and Helen, who stand together to honor the legacy they once feared to lose.
The story unfolds as a sweeping tale of redemption, where wealth, power, and pride are weighed against loyalty, truth, and the bonds of family. It is a drama driven by character, motive, and the slow, painful revelation that sometimes the strongest man in the room is the one who chooses to forgive and to protect those he loves. In the end, the Vadakkanveettil family learns that the real inheritance is not land or money, but the unity and trust that can endure even the darkest of times.
