Satsuki and her husband run an inn in a hot spring resort. Mei, the wife, married Yugo, who was her boss when she was an office lady. Yugo later took over the inn, which is his family's business, and now the couple runs it together. However, the recession has made the business worse, and the poor work attitude of Suzuki, a man who had been working as a servant since the previous owner, has been a major headache for them. One day, Takimoto, a loan shark from whom Suzuki had borrowed money, comes to demand repayment. In a panic, Suzuki comes up with the worst idea: to offer the body of Mei, a beautiful woman with big breasts.
