Kannagi and Kovalan marry in great happiness, but Kovalan squanders their wealth on a dancer, Madhavi. He returns to Kannagi and they travel to Madurai to sell her golden anklet and restart their life. Falsely accused of theft by the king, Kovalan is executed. Kannagi marches to the court and proves her husband's innocence — then tears off her breast and throws it at the city, burning Madurai to the ground.
"She who bears the anklet of gold is the Goddess of Chastity."
