Sethu…

Sethu, a tough college student who leads the Student Union, wins the election. The celebrations erupt into a brawl as tempers flare, revealing his violent temper. This victory marks the start of his rising reputation and foreshadows the conflicts to come.

Following the victory, Sethu meets Abitha, a timid Brahmin girl, and begins to soften. He teases her at first, but her innocence gradually changes his outlook. His friends notice a subtle shift in his behavior.

Abitha's sister returns home after facing dowry abuse in her marriage, carrying a heavy burden of debts. She struggles to repay a loan and rebuild her life with the family's support. This family hardship runs parallel to Sethu's transformation.

Sethu uses his position to help Abitha take an exam she had been denied, showing a protective side beneath his rough exterior. The gesture earns her trust and deepens their growing connection. It underscores the duality of his character.

Sethu awkwardly confesses his love to Abitha, catching her off guard. She is stunned and does not respond, while Sethu misreads her silence as acceptance. The moment plants the seed for a complicated romance.

Abitha becomes engaged to a quiet, submissive priest who ultimately withdraws from the engagement, fearing commitment. This turn of events unsettles her and adds complexity to Sethu's hopes. The social pressures surrounding her choice are revealed through these developments.

Sethu attempts to gift Abitha, but she rejects him publicly. This rejection hurts him and triggers a heated confrontation, even as his friends urge him to reform. The couple’s misunderstandings deepen as pride clashes with genuine care.

In a twist, Sethu uncovers a local brothel and unknowingly frees Abitha’s sister who had been lured into it. The act exposes him to the criminal underworld and deepens Abitha's sister's gratitude. This event also reveals the danger surrounding the women in their lives.

Abitha's fiancé witnesses Sethu’s act and realizes his own shortcomings, telling Abitha that he is not the right match for her. This revelation shifts her perception of Sethu, recognizing his good heart beneath rough edges. The moment clarifies what kind of partner Abitha might truly need.

Desperate and impulsive, Sethu kidnaps Abitha to an abandoned building to express his deep feelings. Abitha, moved by the depth of his love, begins to understand him better. The act marks a turning point in their relationship.

Brothel goons attack Sethu in retaliation, brutalizing him and overpowering him. They strike his head on a rock and leave him near death, ending his moment of cautious happiness. The assault devastates his family and plunges him into a new nightmare.

Sethu is admitted to a remote mental institution where his condition worsens and he undergoes ayurvedic treatment. The staff refuse to acknowledge his sanity, and escape attempts are met with injury. His loved ones struggle to accept his fate.

Abitha’s father and Vasudevan persuade her to marry her former fiancé, believing Sethu is beyond recovery. She is torn between duty, grief, and the desire to secure a safe future. The decision foreshadows further tragedy rather than healing.

Sethu escapes the asylum and limps toward Abitha’s house, only to find wedding preparations underway and the devastating news that Abitha has taken her own life. The revelation shatters him, and he stands speechless at the doorway. The loss seals his broken fate.

Overwhelmed by loss, Sethu is led away by wardens as his friends and family chase after him in tears. He steps into a waiting van, devoid of purpose and reason to live. The closing image mirrors a man who has lost everything he ever fought for.
