Keshu Ee Veedinte Nadhan

Keshu, a driving instructor and the eldest son, carries the weight of supporting his family after their father's death. He works tirelessly with little rest, and his mother's disapproval adds to his stress. The film establishes his emotional conflict between duty to the family and his own desires.

The entire family, including Keshu's scheming brothers-in-law, decides to travel to Rameswaram to perform the last rites for their father. Keshu agrees out of duty, even as his resentment grows. The journey sets the stage for the ensuing conflicts over money and loyalty.

On the way to Rameswaram, Keshu learns that a lottery he bought has won ₹12 crore. The windfall promises a new life free from his in-laws' scheming. He weighs the possibility of escaping with his family to safeguard the winnings.

Aspiring to shield the prize from his relatives, Keshu plans to flee with Rathnam and the kids. He persuades himself that the money could secure their future away from danger. The decision deepens the rift with those who stand to gain from the lottery.

Usha calls her boyfriend Vivek and shares their location, forcing the family to board the tourist bus. Keshu and Rathnam have to adapt to the unplanned ride while the escape attempt falters. The bus becomes the unintended vessel for the escape.

The family returns only to find news and a police presence waiting for them. Keshu reveals there are three lottery tickets, and the winning one is the third—still hidden under his father's ashes. The revelation triggers a frantic search to recover the ticket.

Keshu finds a photo of himself with his ex-girlfriend Leela, which Rathnam misreads as a sign that Keshu hid the winning ticket for Leela's sake. Trust within the family fractures as fear and jealousy mount. The Leela thread casts a personal threat over the lottery plot.

Umesh's alleged affair with the neighbor's daughter surfaces, drawing the mother’s wrath and complicating family dynamics. Keshu accuses his brothers-in-law of being involved in the chaos, while Rathnam grows more suspicious. The family quarrels threaten to derail any chance of peace.

In pursuit of the ticket, Keshu clashes with Biju and accidentally stabs him when he slips on a coconut. The incident triggers police involvement and Keshu's arrest on the spot. Biju survives, and the incident sets the stage for a legal battle.

Keshu spends two weeks in custody before being released on bail after Biju survives and does not press charges. The family is left to cope with fear, shame, and the burden of debts accumulated during the turmoil. Keshu reflects on his responsibilities to his mother and his marriage.

Back home, Rathnam accuses Keshu of past wrongs, but he apologizes and they reconcile. He decides to take care of his mother and to complete their father's last rites, while sorting out the siblings' debt and family dynamics. He resolves to address the long-buried obligations instead of chasing the lottery winds.

Ganapathi calls Keshu on the train and demands funds to cover the mounting debts tied to the lottery win. Keshu pledges to settle everything, even offering to liquidate Usha’s jewelry to raise cash. The tension emphasizes that wealth cannot fix broken relationships alone.

At the Rameswaram temple, Keshu realizes the lottery ticket was hidden beneath the pot with his father’s ashes, restoring the prize to him. Rathnam’s voice returns and her trust wavers between relief and fear. The financial issue seems resolved, but emotional tensions remain intense.

Rathnam regains her voice and confronts Keshu about Leela, suspecting she may be part of his past and the reason he might leave. Keshu tries to calm her and emphasizes using the winnings for good. The couple leaves Rameswaram with unresolved questions about Leela lingering.

The film closes by stating that while the lottery issue is resolved, Keshu's life still grapples with Leela's unresolved situation. The family dynamics shift as they resume life with new awareness of trust and debt. The final line hints at ongoing tensions beyond the jackpot.
