Suryam / Kannan is a playful teenage boy, in the cusp between puberty and adolescent, the son of the famous and well-to-do lawyer Perayya / Varatharajan and Parvathamma / Thangam.

Parvathamma / Thangam wishes to marry off Suryam / Kannan to her brother Chalamayya / Sonachalam's and Bhadramma / Perundevi's daughter Bullemma / Kannamma and invites them to her place.

When Parvathamma / Thangam opposes this, Perayya / Varatharajan, in order to carry on with the wedding, lies to her that Simhadri / Veeramuthu will present a large dowry.

Meanwhile, Chalamayya / Sonachalam wishes to leave home, but Bhadramma / Perundevi, who is in agony, decides to stay back and plans to create hatred between Parvathamma / Thangam and Radha.

When Suryam / Kannan comes back, Parvathamma / Thangam and Bhadramma / Perundevi lie to him that Saroja / Radha had gone to her parents place along with Simhadri / Veeramuthu, without seeking their consent.

At this juncture, Parvathamma / Thangam and Bhadramma / Perundevi further humiliate Simhadri / Veeramuthu to the worst, which drives him to sell his mansion to compensate with much dowry.

At the same time, Simhadri / Veeramuthu parades the dowry items from his home throughout the streets, much to the residents' dismay and reaches Suryam / Kannan's place.

Parvathamma / Thangam realises her error on her deathbed and seeks apology from Suryam / Kannan, Saroja / Radha and Simhadri / Veeramuthu then dies.
