Chellakannu loves Sevuli, the daughter of a cobbler Sengodan, and they plan to elope when Sevuli's wedding arrangements are being made. On learning this, Malaichami berates Chellakannu. Kuyil intervenes and convinces Malaichami to get them married. After the marriage, when Chellakannu and Sevuli are alone in a field, an unseen man kills Sevuli, who managed to bite off his big toe, and leaves having stolen her jewellery. After Sengodan tells Malaichami he found a toe in Sevuli's mouth, Malaichami sees Rasamma's husband without a toe, realises he is the killer and hands him over to the police. Unwilling to live without Sevuli, Chellakannu commits suicide.
