She happens to sing a song in Dorasani's house, which enrages her. Since nobody can have a skill which her daughter has not been able to acquire, she decrees that Mallamma cannot sing if she wants to be alive. However, singing is in her very marrow. After all, she is the daughter of Rajanna, who had inspired hundreds of villagers to revolt against the evil lords through his revolutionary songs.

 

When Dorasani finds Mallamma singing for another time, she decides to hound her and kill. The grandpa wants to take her away, but Mallamma refuses to oblige. It is then when she tells him that she cannot abandon the village where Rajanna meets her every day. Dorasani, who overhears Sambayya telling her that she is Rajanna's progeny, kills him. A heroine that she is, Mallamma stages an escape with the help of the music teacher Kulkarni (Nassar), who tells her that the only way to get rid of Dorsani is to meet Jawaharlal Nehru at Delhi. She sets off to do the same. After overcoming many challenges, she reaches, is taken care of by a young lady, and sets off to meet Nehru with a rose. But, the crowd rushes past her and crushes the rose. She then writes to Kulkarni and tells him that she met a musician who will introduce Mallamma to Nehru in a singing contest on his birthday. Unfortunately, Dorasani catches hold of the letter, captures Mallamma, and locks her in a shed with her music teacher, who tells her the story of Rajanna as follows:

 

After killing over 100 British officers, Rajanna (Akkineni Nagarjuna) is a proud son of a free India. Much to his dismay, he finds the villagers of Nelakondavalli still in servitude and radicalizes them to massacre the oppressors. He slices off the hand of a Nawab and saves a woman from the assault. When the Nawab comes back for revenge, he is killed by the very same woman whom he tried to assault after a revolutionary song by Rajanna. The revolution spreads to hundreds of villages and the nawabs are shaken. Unable to repress the warfare on their own, the local lords seek the help of the evil Razakars. Ever at the forefront to save the village, Rajanna leads a guerrilla warfare with his four comrades (a Muslim, a Tamil Brahmin, a Punjabi and a Maharashtrian) and achieves martyrdom after fighting hundreds of Razakar desperadoes to the finish. Rajanna lives on in the memories of the people of Nelakondapalli.

 

After knowing the story, Mallamma escapes the shed and sets off to meet Nehru. But the singing contest is over. She then sings her heart out. The song attracts Nehru and he comes to Mallamma. He drives away Dorsani and develops the town.

 

The town is shown with a statue of Rajanna.
