Janaki, the daughter of the Pushpagiri Zamindar, marries Ranganna, a commoner, defying her fatherâÂÂs wishes. Enraged, the Zamindar ostracizes them. The couple later has a son, Kalyan, prompting the Zamindar to reconsider and send his nephew Dhananjay to bring them back. However, Dhananjay, harbouring malicious intent, plots to kill the family under the guise of the ZamindarâÂÂs orders. Ranganna is killed in the attempt, but his younger brother, Jaggu, intervenes, allowing Janaki to escape with Kalyan. Janaki entrusts Kalyan to their loyal associate Balaram. To protect Kalyan, Balaram swaps his own children, Anand and Madhavi, with Janaki's and sends Kalyan to Singapore with his brother Banerjee. Meanwhile, RangannaâÂÂs younger brother Jaggu vows revenge against the Zamindar.
Years later, Kalyan, now known as Rajesh, becomes a world martial arts champion. Latha, the ZamindarâÂÂs granddaughter, admires Rajesh and falls in love with him. Meanwhile, Anand competes against Rajesh in a martial arts match to earn money for Janaki's treatment. Despite Rajesh's attempts to protect Anand, the latter sustains fatal injuries. Before dying, Anand reveals his familyâÂÂs true identity to Rajesh. Guilt-ridden, Rajesh quits his career and takes responsibility for AnandâÂÂs family, becoming a taxi driver to support them.
One night, Rajesh rescues Latha from goons and learns that her maternal uncle, Dhananjay, and his son, Maruti Rao, pose a threat to her. Latha asks Rajesh to impersonate her long-lost cousin, Kalyan, to protect her family. Rajesh agrees and confronts Dhananjay and Maruti Rao, disrupting their plans and safeguarding the ZamindarâÂÂs estate. During this time, Rajesh uncovers the impending danger the Zamindar faces from Jaggu. In a confrontation, Jaggu recognizes Rajesh as Kalyan through a tattoo on his chest and learns of the ZamindarâÂÂs innocence.
The situation escalates when Dhananjay and Maruti Rao discover JanakiâÂÂs whereabouts and abduct her along with the entire family. In a climactic battle, Rajesh defeats the villains and rescues his family. The film concludes with Rajesh and LathaâÂÂs marriage, bringing peace to the family.
