Bandai, an successful attorney, and Kyoko, working in a real estate office, start having an affair out of a sudden, although both are married. This way they try to find a relieve from the pressures and fears which arise from their everyday life, in which they feel forced to mask their inner emotions. But their affair is different from others: They are united in love by their wish to die together. Unnoticed by their spouses they meet once a week to make love and to think about their plans to commit double suicide together. They have inexplicably discovered that perfect strangers may also mean perfect partners in death.
