Ooty Varai Uravu

Vedachalam is a wealthy businessman in Ooty who secretly has a second family with Sivakami and their daughter Vijaya. Sivakami dies, and Vijaya resolves to expose Vedachalam's double life with proof of the marriage. She sets out for Ooty to confront him.

The first Vijaya, Vedachalam's daughter by Sivakami, journeys to Ooty armed with the proofs of his second marriage. She prepares to confront her father and demand recognition. The confrontation sets the main conflict in motion.

A second Vijaya, the daughter of a wealthy zamindar, shares her name with Vedachalam's daughter. Her greedy uncle schemes to marry her for her wealth, and she runs away to avoid the match. This creates a parallel plot that intersects later with Vedachalam's family.

On the road to the railway station, the second Vijaya's taxi runs over the first Vijaya. The taxi driver refuses to help the injured woman. Ravi happens to be on the same road, arrives at the scene, and arranges for the first Vijaya's hospital treatment.

The second Vijaya reaches the railway station and discovers the first Vijaya's luggage, including evidence of Vedachalam and Sivakami's wedding. Realizing she could pose as Vedachalam's daughter, she decides to approach him. She chooses to impersonate a relative to secure shelter and support.

Ravi encounters the second Vijaya on the train and is unsettled by the revelation of Vedachalam's secret life. He chooses not to reveal his identity, avoiding further complications at that moment. The two begin a tense, delicate relationship.

The second Vijaya meets Vedachalam and confronts him. He accepts the charges and introduces her to Sivakami and Ravi as a friend's daughter. Vijaya agrees to pretend to be the friend's daughter to protect her father and the family name.

The first Vijaya loses her proof of birth and seeks help from her boyfriend Sundaram. Sundaram's father is opposed to love marriages, so Sundaram shelters her in a hotel temporarily while he forges a way to help. The situation ties the two love stories to a shared destiny.

Tirupathy, Vedachalam's family physician, spots a 'Missing' advertisement placed by Vijaya's uncle and begins to investigate her identity. This creates pressure to uncover who Vijaya really is. Meanwhile, Ravi secretly meets his real sister in the hotel with Sundaram, coordinating a plan.

Sundaram's father agrees to help the plan, and Sundaram, his father, and Vijaya (now under the alias Rathi) move to Ooty. Ravi continues to guide the plan, maintaining the illusion to push Vedachalam toward recognizing his daughter. The group now consolidates the two families.

Ravi reveals to Sundaram's father that Vijaya is connected to Vedachalam and advises arranging a quiet marriage for Sundaram and Vijaya. The plan aims to secure the wealthier family's blessing without exposing the deception. Both families prepare for the double wedding.

Sundaram's father agrees to conduct both weddings together at his expense to minimize scandal. The plan is to have Ravi wed the other Vijaya while Sundaram marries the first Vijaya, blending the two families in one ceremony. The social tension rises as everyone prepares for the big day.

A conflict erupts when Vijaya is kidnapped by her uncle just as the weddings approach. Thirupathy, Ravi, and Sundaram launch a rescue operation to bring her back to the venue. The dramatic interruption threatens to derail the ceremonies.

The trio's rescue brings Vedachalam to the venue, where he is forced to confront the truth about his double life. Ravi steps forward and clarifies the true identity of Vijaya, ensuring the right daughter is recognized. The families confront their past and prepare for reconciliation.

Sundari forgives Vedachalam, accepting Vijaya into the family. With the truth out, both marriages go forward, and the families are reconciled. The two weddings are celebrated, and the couples begin their new lives together.
