The Portuguese authorities aim to set up an army base in Vasanthapuri, a territory in Tamil Nadu, India. They approach Diwan, the local ruler, and offer to make him king if he agrees to carry out the plan. Diwan accepts, despite the local people's protests.

In response to the protests against the Portuguese plan, Diwan begins heavily killing the local people to suppress opposition. His actions cause widespread outrage and deepening unrest among the villagers.

Ananth, whose father was killed in a shootout during the conflict, vows to take revenge for the atrocities. His determination is fueled by the death of his father and the violence inflicted upon his community.

Chithralekha, the princess of Vasanthapuri, is living in Zurich, unaware of the danger threatening her homeland. She reads a newspaper and learns about Bharat, a talented student from Vasanthapuri who recently excelled at the University of Bern.

Chithralekha finds Bharat's photograph in a local paper and feels interested in meeting him. She secretly meets him at a club, congratulates him for his achievements, and introduces herself as 'Vasanthi'. They quickly develop a romantic interest.

Bharat and Chithralekha enjoy their time touring Europe, developing a strong bond. Their relationship blossoms as they share adventures and get to know each other better.

Chithralekha discovers that her homeland is in danger due to Diwan's plans and the violent conflict. She decides to return to India to help save Vasanthapuri, with Bharat vowing to accompany her.

During their flight back to India, a flight attendant reveals that Diwan intends to marry the princess and plans to meet her at the airport. Chithralekha tries to escape, but Bharat fights the attendant, causing the plane to spin and plunge into the sea.

Both Bharat and Chithralekha are presumed dead after the plane crash but are found unconscious on a remote island. They are cared for by local doctors who help them recover and arrange their return to mainland.

Bharat realizes that 'Vasanthi' is actually Princess Chithralekha. However, she advises him to see her only as his love interest, keeping her royal identity a secret to protect herself and their mission.

Bharat and Chithralekha arrive at Ananth's house. To protect her identity, Chithralekha disguises herself as a regular girl. Only Bharat knows her true royal identity as the princess.

Diwan's tyranny intensifies as he starts killing protesters once again. Ananth dies in the shootout, and his mother succumbs to shock from his death, further motivating Bharat and his allies to fight against Diwan.

Bharat, Chithralekha, and their friends seek shelter in a bar and plan their strategy to oppose Diwan's forces. They begin secretly dealing with Diwan and his army to protect the people and restore peace.

Bharat reaches Diwan's castle and fights him in a fierce battle. During the fight, Diwan kidnaps Chithralekha and escapes in a hot air balloon. Bharat pursues and ultimately kills Diwan, bringing an end to his tyranny.

With Diwan defeated, peace is restored to Vasanthapuri. Bharat and Chithralekha get married, uniting their love and the hope for a brighter future for their homeland.
