Two housewives, wounded by their husbands' betrayals, meet by chance. They decide to carry out "exchange murders" and work towards the perfect alibis. Under what they know to be perfect plans, they kill each other's husbands. Although the police are able to prove that they're guilty, these two women are found innocent by the court of law.
On the first full moon of January, in the town of Ha-pyung, there is a festival going on in the yard of Shin Chi-gyu, the town's biggest landowner. They are playing yut, a game of throwing four short sticks. The winner of the game is Ok-bun's husband, Lee Bang-won. Having no money, Ok-bun and Bang-won had been tenant farmers on Chi-gyu's land. With their winnings, they try to start their own business. Chi-gyu had always been drawn to Ok-bun. When Bang-won leaves, Chi-gyu comes on strong to Ok-bun. Ok-bun waits eagerly for her husband's return but Bang-won has failed in his business and returns a pauper. As their dreams go up in smoke, Ok-bun falls into deep despair.
