Stolen Cash, Broken Card, Bloody Payback

The cash machine at one bank branch is broken. Yuna goes there to draw some money. The customer-service line has already given her a hard time, and then the machine keeps her card, and 10,000 disappears from her account for no reason she can find. Nobody at the bank will help. She is close to breaking down in front of the machine when it starts pushing out bills, and does not stop, until the floor around her is covered with cash. The bank has just treated her unreasonably, and the money at her feet comes to something like ten million. The card turns out to matter more than the cash, because her mother's life comes to depend on it, and the bank freezes her out entirely. Her answer is to use the bank's own tactics against it, beginning with the staff and their manager, who by then have set up a scheme of their own against her.
