Kemmel, a sculptor with a troubled nature, wonders, as he approaches his fortieth birthday, whether he has created any truly significant work.

It's Saturday lunchtime in a small town near Munich and there's not much going on. The local bank is already closed, doors and windows are barred. The few passers-by in the main shopping street do not notice that a violent crime is being committed behind these windows.

The more gaps in the police's chain of evidence, the more serious the decision to tell the truth and risk their own happiness.
