The small local factory run by the husband has been forced into a very tough business situation due to rising costs caused by the recent high yen inflation. One day, when the husband is finally in a difficult position to make the payment at the end of the month, his faithful and beautiful wife Kanna suddenly remembers something and suggests that they go and consult about a loan with a man named Iguchi, a classmate of the husband's who is rumored to have recently made a huge fortune from his video distribution work. The couple swallows their shame and goes to consult about a loan... but there, he proposes that they "use their wife as collateral in exchange for the loan."
