Abhiram and his friends, studying at an educational institute run by Srinivas, stumble upon an old box of cassette tapes containing mathematics lessons. Alongside the tapes lies a receipt addressed to A. M. Kumar from Sozhavaram, dating back to 2000. Upon inquiry, they discover that Kumar is Kadapa’s district magistrate, and that the man in the video is Bala.
The plot then shifts back to 1993, a time when private institutions were multiplying while the government struggled to sustain public colleges. Five years later, with government colleges shutting down due to a shortage of lecturers, the poor are left with little access to higher education. Bala is sent to a government junior college in Sozhavaram to teach mathematics, and the college’s attendance drops, threatening its continued existence.
Bala organizes a village meeting to emphasize the importance of education, rallying the villagers and their children around him. He enlists help from an ex-student, Muthu Pandian, to assist with teaching. He also finds love with Meenakshi, the biology teacher at the institution, and begins to challenge the caste barriers that divide the students. The final board exams see all the students pass with first-class distinctions. Srinivas tries to lure Bala away with a lucrative job offer to keep students in private institutions, but Bala refuses. In response, the government’s Education Ministry moves to roll back the regularization of lecturer positions, leaving Bala without a post.
Undeterred, Bala starts private tutoring in an open field. Thirupathi, a vociferous opponent, prods the villagers to drive him away. Bala fights back, but is arrested and tortured in custody and then dumped back into the village with rumors that he misused government funds. His ex-students come to his aid, and he ends up returning to his hometown, where he relies on his father Narayanan for support. After a period of hardship, Bala resumes tutoring at home, encouraged by Ansari, a former colleague. Meenakshi returns and decides to marry him.
The story follows a budding connection to a younger generation: a young boy with a strong will to study but hampered by poverty and pressure from his father to earn money. Bala records his lectures on cassette tapes and sends them to Bhupathi, Abhiram’s grandfather, a photographer in Sozhavaram. Bhupathi begins to stage special shows for students at 6 p.m. in a nearby theater, where Bala’s lectures are broadcast. To clear doubts and interact with students, Bala visits the village on Sundays in the guise of a drama artist. Thirupathi tries to disrupt the exams, but Bala and the students persevere, with Muthu Pandian guiding the way as the community slowly embraces the educational shift.
In the present, the theater becomes a coaching center for the underprivileged, built and run by the alumni who remember Bala and his friends’ efforts. Bala and Meenakshi have gone on to establish an education initiative called Ansari School of Knowledge in Ooty, dedicated to providing free education for the underserved.
At the felicitation ceremony for Abhiram and his peers, Abhiram secures a top rank in the JEE Mains, finishing among the Top 100 with guidance from the older students and Bala’s taped lectures. In his speech, he credits Bala for the victory and, to honor that debt, publicly releases Bala’s tapes, thereby exposing Thirupathi and signaling a lasting victory for educational reform. The film closes on a note of renewed hope: education as a path to equality, supported by a community that refused to give up and a boy who dared to dream beyond poverty.
