Bettina Maurer, mayor of a small town, is cut by a car while crossing a street. She shouts insults at the driver before entering the anteroom of a small bank branch to withdraw money shortly before midnight. But then her EC card gets stuck in the machine. At this moment Martin, visiting from Berlin, enters the room. He is also in a hurry and wants to solve the problem at the ATM quickly: So he poke around in the card slot with a hairpin - there is a short circuit. But not only is the machine out of order afterwards, the electronically secured door also no longer opens. And so the two are now stuck and all attempts to get help fail.
