Vaathi (transl. Teacher) is a 2023 Indian bilingual period action drama film written and directed by Venky Atluri. The film was simultaneously shot in Tamil and Telugu with the latter version titled as Sir.^[3][4] The film star Dhanush in main lead as a School Teacher.

Abhiram and his friends, students at an educational institute run by Srinivas (Samuthirakani), are preparing for the engineering entrance examination. They come across an old box of cassette tapes containing mathematics classes with a receipt accompanying it in the name of Kumar from Sozhavaram, dating back to 2000. After inquiry, they discover that Kumar is the district magistrate of Kadapa, and later Kumar discloses that the man in the video is Balamurugan 'Bala' (Dhanush).

The plot moves back to 1993, when many private institutions sprang up and the government was finding it difficult to sustain interest in public institutions. Five years later, with government colleges shutting down due to a shortage of lecturers, the poor who cannot afford private institutions are left with little access to higher education. Srinivas, the president of the private colleges association, hatches a plan to adopt all the government colleges and send junior lecturers to those colleges, while obtaining support from the government to stop the regularization of fees by the government. Bala is one such lecturer, who is sent to a government junior college in Sozhavaram to teach mathematics. Bala finds that the college is lacking in attendance and due to this the college may be shut down soon.

Bala organizes a meeting with all the villagers and their children and explains the necessity of education, thus making the children and parents realize its importance. The students then start to come back to classes with Balu handling additional classes and engaging an ex-student, Muthu, to teach as well. Meanwhile, Balu falls in love with Meenakshi (Samyuktha), the biology teacher at the institution. Bala notices caste differences among students and comes up with a ploy to eliminate it. The board exams take place, with all the students passing in the first class. Srinivas tries to lure Bala away with a lucrative job offer to stop students from moving back to government institutions rather than private institutions. Bala refuses, and Srinivas acts via the education minister to take back the positions offered to lecturers at government junior colleges and recruit new ones, leaving Bala without a job.

Later, Bala takes private classes in an open field in the village, prompting outbursts from Thirupathi, who instigates the villagers to drive him away from the village. Bala fights back, but is arrested and tortured in custody. He is dropped back into the village soon afterward, where the villagers are asked not to help him, indicating that he misused government funds. Bala's ex-students help him get back to his hometown, where he becomes dependent on his father, Narayanan (Naren), who works as a driver. After recovering, he takes up tutoring at his home on the insistence of Ansari, his former teacher, after many failed job interviews at private junior colleges. Meenakshi arrives and decides to marry him. They see a young boy who is willing to study but is unable to do so due to poverty. His father is constantly pressuring him to earn money.

Bala gets an idea and records his lectures using cassette tapes and sends them to Bhupathi (Abhiram's grandfather), a photographer in Sozhavaram. Bhupathi runs special shows for students at 6 p.m. every day in the nearby theater, where Bala's lectures are played. To clear doubts and interact with students, Bala visits the village, under the guise of a drama artist, each Sunday. Thirupathi tries to stop the students on the day of the exam. Bala fights them off and the students perform well, clearing the exams with Muthu scoring the first rank and revealing himself as Kumar. Thirupathi offers money to all the students, promising them sponsorship for their further studies on the condition that they endorse his institution. Bala asks the students to agree to it and asks them to help needy students in the future after they climb the socio-economic ladder.

In the present Kumar continues his story, saying that the theater where they studied is now a coaching center for the underprivileged, developed by the old students, who take turns teaching each year. While Kumar does not know the current whereabouts of Bala, it is shown that a still living Bala and Meenakshi have opened a school, Ansari School of Knowledge, to provide free education for the underprivileged at Ooty.

In an alternate ending, Abhi and his friends also achieved ranks within the Top 100 in the JEE Mains, with Abhi securing the first rank, guided by Kumar, the old students, and Bala's recorded tapes. At their felicitation ceremony, despite being coerced by Thirupathi, Abhi credits Bala for his achievement. In addition, he unveils Bala's tapes publicly, thus exposing Thirupathi.
