Synopsis.
Towako leads an idle life alongside Jinji Sano, in his fifties, a man about fifteen her senior, whom she despises and belittles at the slightest opportunity. The latter endures her remonstrances without flinching and alone provides for the needs of the household through hard work as a blue-collar worker. Towako takes Makoto Mizushima as her lover, but lives in the painful memory of her relationship with Shun'ichi Kurosaki which ended abruptly eight years earlier. One day she dials Kurosaki's number but hangs up immediately. Following this phone call, a police inspector visits her and tells her that Kurosaki disappeared without a trace five years ago. When Towako catches Jinji spying on her as she walks out of a love hotel with her lover, she begins to suspect that Jinji is responsible for Kurosaki's disappearance.
