The short story takes place in a land ruled by a semi-barbaric king. Some of the king's ideas are progressive, but others cause people to suffer. One of the king's innovations is the use of a public trial by ordeal as an agent of poetic justice, with guilt or innocence decided by the result of chance. A person accused of a crime is brought into a public arena and must choose one of two doors. Behind one door is a lady whom the king has deemed an appropriate match for the accused; behind the other is a fierce, hungry tiger. Both doors are heavily soundproofed to prevent the accused from hearing what is behind each one. If he chooses the door with the lady behind it, he is innocent and must immediately marry her, but if he chooses the door with the tiger behind it, he is deemed guilty and is immediately devoured by it.
