Baptista, a wealthy merchant of Padua, has two daughters: Katherina and Bianca. Because of Katherina's shrewish disposition, her father has declared that no one shall wed Bianca until such time as Katherina has been married. Lucentio of Pisa, one of many suitors to the younger and kinder Bianca, devises a scheme in which he and Tranio (his servant) will switch clothes, and thus disguised, Lucentio will offer his services as a tutor for Bianca in order to get closer to her.

A marriage is arranged, and Petruchio immediately sets out to tame Katherina through a series of increasingly worse tricks. This involves everything from showing up late to his own wedding to constant contradictions to whatever she says, even to the point of claiming that the sun is in fact the moon. After many trying days and nights, an exhausted Katherina is indeed "tamed" into docility.
