Adutha Saattai

Dayalan is introduced as a Tamil lecturer who is well‑respected and loved by the students for his caring approach and open‑mindedness. His colleagues, especially the college principal Singaperumal, hate him for reasons tied to ego and campus politics. The campus atmosphere is tense as students rally to his inclusive philosophy.

Dayalan forms a personal bond with his colleague Pachiammal, sharing similar ideologies and mutual respect. Their relationship grows and they eventually marry, deepening Dayalan's commitment to improving college life. The marriage strengthens his resolve to advocate for student empowerment.

The college is divided into two prominent caste groups, leading to frequent clashes among students. Podhumponnu is seen more favorably by her peers than Aadhi, who comes from a poor family, adding to the social tension Dayalan aims to bridge. Dayalan works to calm tensions and promote unity across caste and class lines.

Dayalan proposes forming a Student Parliament to handle day‑to‑day college activities such as cleanliness and infrastructure. The plan aims to empower students from all backgrounds and reduce conflicts, though some lecturers and the principal oppose it initially. Gradually, more staff begin to see its potential.

Local media outlets start praising Dayalan for his efforts to empower students and promote unity. The positive coverage improves the college's public image and boosts the students' confidence in campus initiatives. The college gains wider recognition for its progressive approach.

Dayalan initiates a campus interview process, inviting organizations to the college so that disadvantaged students have a fair chance at placement. He meets with multiple organizations to set up recruitment drives and showcases the college's improved ecosystem. The initiative is presented as a model for other arts and science colleges.

Aadhi, Podhumponnu's classmate, receives a good job offer that could improve his family's finances. He hopes to uplift his loved ones and change their circumstances. Dayalan's placement drive makes opportunities feel more attainable for students like Aadhi.

Even as many lecturers support Dayalan's ideas, Singaperumal's ego keeps him from backing the reform. He starts showing anger toward students and suspends Aadhi from his class. Pazhani, angered by the decision, also leaves the class in protest.

Angered by the disciplinary actions, Pazhani and Aadhi ride away on a motorcycle and meet with a serious accident on the road. Aadhi dies as a result, and Pazhani is badly injured. The tragedy shocks the entire college community and sets off a chain of emotional consequences.

The death of Aadhi weighs heavily on Singaperumal, triggering a personal transformation. He begins to accept responsibility for the events and the consequences of his actions. The evolving leadership dynamic unsettles the old order on campus.

Caste leaders arrive at the college to protest under the banner of caste-based interests, reportedly seeking money from the management. Dayalan secretly records their conversation and disseminates it to the students, exposing their true intentions. The revelation galvanizes student unity against exploitation.

Students unite and eject the caste leaders from the campus. Singaperumal offers a public apology, accepts responsibility for Aadhi's death, and promises to support Pazhani in caring for Aadhi's family. The college begins to heal as leadership acknowledges past failures and commits to reform.
