Ishida Tetsuko is a lawyer who earnestly lives to help people. On the other hand, Kotani Natsuko is an exceptionally self-centered swindler who lives to turn people's goodwill into money. The two ladies are like opposite sides of the same coin. Because they are relatives, Tetsuko is trapped into working at Natsuko's request. Natsuko keeps getting into trouble because her tricks are always half measures and Tetsuko's role is to clean up after that. Their troubled relationship has endured for 20 years and they eventually start to become indispensable comrades to each other. While coming between Natsuko, who is outrageous yet somehow impossible to hate, and her “victims”, Tetsuko realises there is are things more important than money and winning trials. Life did not go as planned, but she could have done worse and there is value in embracing life every day.
