Lieutenant Colonel Geeta Rani, an officer in the Indian Army, takes voluntary retirement and joins a struggling government school in Puthur as the new headmistress. She is determined to transform the poorly functioning school and bring a positive change to the educational system.
Upon arriving in the village, Geeta Rani overhears villagers and even an auto driver speaking negatively about the school. Undeterred, she visits the school undercover to assess the condition of the campus, staff, and environment. She finds widespread neglect, lack of discipline, and corruption. During an attempt to admit a child, the Assistant Headmaster demands a bribe of ₹2,500, even though government school fees are only ₹230 per annum. When challenged, he refuses to admit the child.
Geeta Rani immediately asserts her authority by ringing the school bell and assembling students and staff for a warm-up session. She confronts a petty shop outside the school selling tobacco and gutka to students. When the shopkeeper resists, she destroys the toffee jars and warns him, forcing the shop to close.
She organizes a parents' meeting, urging them to support the school's development. She also contacts the Public Works Department to send workers for cleaning and maintenance. Soon, the school is refurbished, and students begin showing interest in academics and extracurricular activities.
Geeta Rani's progress, however, draws the ire of Ramalingam, chairman of the GSV Group of Schools, a private school network who sees her as a threat. He sends goons to attack her at the school, but she bravely fights them off. Ramalingam also files a fake complaint, resulting in a surprise inspection by the District Collector. The Collector, impressed by the transformed school, praises Geeta Rani and advises her to remain steadfast.
Later, Geeta Rani learns that 89 students in the 9th standard have failed, resulting in them dropping out and indulging in manual labour. After reading about a student who committed suicide due to academic failure, she interrogates the teachers. They claim the students are "good for nothing". Disagreeing, she promotes them to the 10th standard without informing the authorities.
During the summer vacation, Geeta Rani visits the school to prepare for the upcoming SSLC exam results. She meets the seniormost teacher Susheela, revealed to be the mother of Kathir — Geeta Rani's late boyfriend, with whom she shared a dream of reforming the education system.
Suddenly, Geeta Rani is arrested for promoting failed students without permission. The students, parents, and staff (all of whom were at first opposed to her due to her military style disciplinarian attitude and intervention in a fight between students from 2 different caste groups, thus derogatorily referred to her as a rakshasi) now assemble in front of the police station, demanding her release. The next morning, the SSLC results are declared. Out of the 82 students, 79 pass, and 14 score over 400 out of 500.
The film concludes with Geeta Rani's success in transforming the once-neglected government school into one of the best institutions in the state, fulfilling her and Kathir's shared vision for quality education.
