Set in the 1940s, in Nelakondapalli village, Adilabad district, Mallamma (Annie) is a beautiful girl, who is born with an exceptional talent in singing. She is taken care of by an elderly man in her village.
On one occasion, the elderly man and Mallamma visit the house of the Dorasani (Shwetha Menon) to seek her permission for Mallamma's education. Dorasani hears Mallamma's song there and gets very angry as her own daughter can't sing. She bans Mallamma's song and threatens her with death. When Mallamma accidentally sings again, her house is intentionally set on fire and the elderly man is killed.
Mallamma is saved by a sincere man, who is a capable music teacher. When Mallamma comes to know that only Jawaharlal Nehru in New Delhi can save her, she sets out to Delhi on a lonely journey. When she is attacked in Delhi by Dorasani's men, she loses hope and wants to end her life.
The inspirational story of Rajanna (Nagarjuna) is then revealed to her by the music teacher. She is inspired by the heroic deeds of Rajanna and valiantly goes about facing her difficulties. How does she do it?
