Naga Raju is a greedy man who values wealth over morals. His family consists of his devoted wife, Meenakshi, who is pregnant, and their two young sons. Despite his familial obligations, Naga Raju engages in unethical practices to achieve his financial goals.
In contrast, Contractor Devi Prasad is a principled man. He has two young sons: Kalyan, aged five, and Mohan, aged two. During Mohan's birth, Devi Prasad’s wife, Sarada, suffers a mental breakdown and is hospitalized. Tragedy strikes when Kalyan dies in a car accident. However, Sarada regains her mental faculties around the same time. Distraught over the loss of his son and unwilling to tell his recovering wife, Devi Prasad follows the advice of Satyam, and buys a child of the same age as Kalyan to present as her own.
Simultaneously, Naga Raju, driven by greed, forcibly obtains Meenakshi's thumbprint on divorce papers and expels her from their home. He retains custody of their elder son, whom he sells to Satyam for financial gain. Meenakshi, now destitute, gives birth to a daughter, Rani, and raises her alongside her younger son, Ramu. Despite facing numerous hardships, she ensures both children receive an education. However, Meenakshi falls seriously ill and requires medical treatment, which Ramu cannot afford. In desperation, he resorts to unethical means to earn money.
Meanwhile, Kalyan, raised by Devi Prasad, excels in academics and sports, enhancing his adoptive father’s reputation. Mohan, who attends the same college as Rani, falls in love with her, further intertwining the fates of the two families.
Devi Prasad wins the contract for the tender of the Nagavali Dam, which infuriates Naga Raju. In retaliation, he partners with another unscrupulous man, Ramesh, and they plan to pollute the raw materials supplied for the dam to deceive Devi Prasad.
Ramu meets a college girl named Latha, while Kalyan meets a girl named Varalakshmi, and both couples fall deeply in love.
However, the construction of the Nagavali Dam faces a setback when it collapses in the final stages. The incident, coupled with government pressure, severely affects Devi Prasad's health, leaving him bedridden. He suspects foul play and says so to Kalyan. As he nears death, he entrusts his younger son Mohan and his assets to Kalyan, but even on his deathbed, he does not reveal the truth about Kalyan's origins.
One day, Kalyan discovers an agreement in which Satyam had bought a boy for Devi Prasad. Suspicious, Kalyan confronts Satyam, who, unable to avoid the truth, reveals that Kalyan is not Devi Prasad's biological son. Enraged by the revelation that his parents sold him for money, Kalyan grapples with his emotions. The rest of the story unfolds as Kalyan's journey to uncover the truth and reconcile with his past continues.
