In Chennai, Mani, a cab driver, leads a double life, telling his wife Subbulakshmi that he works as an insurance salesman while secretly driving a taxi at all hours. One day, he picks up Gautham, the spoiled son of a recently deceased businessman who is locked in a feud over the control of his father’s estate. A sudden collision during Gautham’s hurried escape leaves the back seat of Mani’s cab bearing a crucial misfortune: Gautham has misplaced the key to the vault where his father’s will is kept.
Mani makes a dangerous choice to hide the key from Gautham, not realizing the storm he’s inviting into his own life. As Mani hunts for the key, [Gautham] visits Subbulakshmi’s home and reveals the truth about his job and his family’s struggle, a truth that she never expected to hear. The revelation shatters their precarious balance, and Subbulakshmi leaves Mani, taking their young son with her. With his family fractured and his deceit exposed, Mani’s sense of himself begins to fracture as well, and he resolves to seek vengeance against the man who upended his life.
The feud between Mani and Gautham escalates into a personal battle over property and pride. They vow to eliminate each other as obstacles stand in the way of their ambitions. When Mani fails to kill Gautham, his anger turns toward Gautham’s girlfriend, Pooja. As Mani closes in, a dramatic chase culminates in a near miss when Gautham intervenes and saves Pooja, forcing Mani into a confrontation that ends in a brutal but inconclusive car duel. Both men walk away, nursing their wounds and darker resolutions.
Meanwhile, Mani slips deeper into self-awareness as he is picked up by the law and questioned about his recent actions. At the police station, Subbulakshmi speaks plainly about the flaws she has seen in him, and Mani’s eyes finally begin to open to the consequences of his choices. Gautham steps in to bail him out, moved by the realization that life outside of wealth and revenge still holds people who care.
The two men forge a fragile reconciliation that centers on a shared birthday, a small, intimate moment that hints at the possibility of redemption. Mani returns the key to Gautham, having hidden it earlier in the sofa, and confesses that the torn will on the wall had been a fake. The revelation shakes the foundations of both men’s plans and their sense of justice, guiding them toward a new kind of honesty.
As the story shifts toward its final acts, Mani races to the railway station in a bid to stop Subbulakshmi and his son from leaving him forever, only to arrive too late. He returns home to find a birthday cake laid out as a quiet, hopeful sign that life can still surprise him. The moment feels almost dreamlike, and he discovers that his family’s presence—Subbulakshmi and their child—was brought back by [Gautham], who has learned to value human connections over material gain.
In the aftermath, [Gautham] confronts the man who has long held the keys to his family’s fortune, the custodian [P.K.V Hariharan], and confesses that he no longer wants his father’s wealth—even as he prepares to step away from the estate. A new encounter awaits when his car collides with a woman driving another vehicle. The initial friction gives way to warmth as he apologizes, asks for her number, and promises to cover the damages. The film closes on a hopeful note: two strangers who have learned to see life beyond money share a smile and drive off together, hinting at a fresh romantic beginning.
