The movie primarily takes place in two locations: Chennai, where Raja faces pressure from his father over an arranged marriage, and Ooty, the hill station where the main events unfold among tea estates. Ooty serves as the setting for Raja's disguise as a driver and his romance with Indhu.

Ooty is depicted as a cool hill station famous for its tea estates and scenic landscapes. It represents a space of freedom and romance, contrasting with Chennai's social expectations. The setting enables Raja's disguise as a driver and the evolving relationship between Raja and Indhu.

The movie explores three major themes: Identity and Masquerade (disguises, mistaken identities, characters hiding their true selves), Love and Constraints (romance blooming amid family duty and personal choice), and Wealth and Deception (villains scheming to seize wealth, contrasted with generosity and family bonds).

Raja is the rebellious son of a retired colonel who flees to Ooty after opposing his father's arranged marriage choice. He disguises himself as a driver to win Indhu's heart and uncover threats against her family. His arc involves balancing pride with vulnerability while ultimately revealing his true parentage and protecting his family.

Indhu is Viswanathan's daughter and the intended bride for Raja in the arranged marriage. She is kind-hearted and navigates social pressures of an arranged marriage. As the story progresses, her feelings shift toward Raja, leading to a sincere romance while she remains unaware of the deception surrounding her engagement.

Vasu is a con artist and street-smart trickster who befriends Raja in Ooty. He helps Raja in his disguise while also pretending to be Indhu's fiancé to protect secrets. Though he uses wit and tricks for comic situations, he forms a genuine bond with Raja and Meena, toggling between trickster and loyal ally.

Viswanathan is a wealthy tea estate owner in Ooty known for his generosity and shrewdness. His wealth becomes a key plot point as villains scheme to seize it. He is misled by mistaken identities and the kidnapping subplot tests his patience and loyalty. His lineage and relationship with Raja are ultimately clarified and restored.

The central family conflict involves Raja rebelling against his retired colonel father Chandrasekar, who selects a bride for Raja that he dislikes. Raja flees to Ooty to escape the arranged marriage, only to discover the chosen bride Indhu is exactly the woman he falls in love with, creating a chain of comic misadventures.

The film heavily relies on disguises and mistaken identities. Raja hides his true self by living as a driver, while Vasu pretends to be Indhu's fiancé. A twin brother subplot and villain manipulation amplify the deception. These masquerades create comic situations and ultimately reveal true loyalties.

The main villains are Kasinathan, Viswanathan's criminal twin brother recently released from jail, and his accomplice Shankar. They scheme to grab Viswanathan's wealth by abducting him and manipulating events. Their counterfeit plots collapse as the truth about lineage emerges, leading to their arrest.

The movie blends romance, drama, and comedy with a light-hearted tone despite featuring a kidnapping plot and criminal schemes. These elements are treated comically rather than with genuine threat. The narrative moves as a playful comedy of errors with steady pacing, combining humor, romance, and a happy resolution.
