All's Well That Ends Well is a Comedy (though sometimes called a "Problem Play"). It is summarized as:
Helena, a ward of the Countess of Rousillion, falls in love with the Countess's son, Bertram. Daughter of a famous doctor, and a skilled physician in her own right, Helena cures the King of France—who feared he was dying—and he grants her Bertram's hand as a reward. Bertram, however, offended by the inequality of the marriage, sets off for war, swearing he will not live with his wife until she can present him with a son, and with his own ring—two tasks which he believes impossible. However, with the aid of a bed trick, Helena fulfils his tasks, Bertram realises the error of his ways, and they are reconciled.
