A financially struggling lower middle-class family wins a car in a raffle draw, turning their ordinary life into a moment of astonishment. They celebrate the prize with disbelief and relief as the gift promises to change their fortunes. The win attracts attention from outsiders who want a share of the newly acquired asset. At home, the family begins to plan how to use the car for better days.

The car prize brings the attention of the authorities as the man delivering the car is summoned to the police station. There, Agalya asserts that the car belongs to her family, while Durai appears claiming a stake. The police ask to see the car bill to determine ownership, setting up the central dispute.

A flashback reveals that Durai did not buy the jewels for Agalya; the jewels were meant for someone else. Agalya admits that she filled the winning coupons, muddying the ownership of the prize. The revelation shows the conflict over the car is entangled with crime and manipulation. The demand for the bill intensifies the clash.

Thenmozhi and her groom visit as part of their marriage arrangements, insisting the car be settled before the union. On their date, they collide with an elderly man, and in a panic they hide his body in the car trunk. The shock grows when they learn the car is currently at the police station, linking the incident to the ongoing dispute.

Durai's men break into the jewel owner's house to steal the bill that could prove ownership. Agalya takes the bill first and proposes a 50–50 split of the car once it is retrieved. They stage a fake owner to present as the real one, but the ruse backfires when the real owner is also tracked down, revealing Agalya's central plan.

Agalya is taken to a police lodge to face potential punishment. A police officer tries to coerce her, attempting to force himself on her. She resists, escapes, and later vows to expose the officer and publicize the abuse to ensure accountability.

Outside the lodge, Agalya asserts that the entire scheme was her making. The group opens the car trunk and discovers the body is no longer there, raising new questions. They are briefly kidnapped by police but manage to escape the tight spot.

Meanwhile, Thenmozhi's marriage plans still move forward despite the chaos. The family clings to hope of a peaceful future as the car saga continues to unfold. They prepare for the wedding, trying to restore normalcy.

A new twist reveals that the man who was in the trunk did not die after all. He has somehow survived or escaped, altering the perceived threat. This revelation reshapes everyone's understanding of ownership and justice surrounding the car.

The authorities' investigation intensifies as the survivor's emergence comes to light. The family faces pressure and scrutiny, but decides to press on with the wedding. Public exposure of corruption begins to unravel the deceit around the prize.

The truth about the survivor from the trunk surfaces, confirming he is alive and linked to the car ordeal. The car and jewels scheme are unraveled in the process. The family finally begins to see a possible resolution.

The story ends with the family finding happiness as Thenmozhi marries and the chaos surrounding the car subsides. The family begins a new normal, having endured deceit, danger, and manipulation. The film closes on a note of resilience and renewed hope.
