Siva Rao (Veera Santhanam) is a Thol Pavai puppeteer. He and his family go around villages, performing the art for his survival. He is struggling to make both ends meet.

When they land up in Tirunelveli, a rich man Chelladurai (S. Theodore Baskaran) decides to support the family, for his young grandson Jothi (Jai) loves the art and their family. Thamizharasi (Nandhagi), Siva Rao's granddaughter, is enrolled in a local school, who grows up and works hard to pass out in flying colors in her higher secondary.

Even as she gets admission in an engineering college in Pune, Jothi and Thamizharasi develop affinity for each other. Unable to leave her, Jothi rapes her, which changes her life. As a result, Jothi is forced to leave the village by his grandfather, to live with his dad. Jothi returns after a couple of years to see Thamizharasi nowhere. The rest is all about how Jothi travels from pillar to post to reach out for Thamizharasi and repents for his acts that altered her life all together.
