Leonora is a housewife who put her career as a violinist on hold years ago to care for the couple's son, Johan, who is finally in remission and graduating from high school soon.

Leonora suspects that Christian is having an affair with Xenia, a young architect with whom he works on a current contract.

Looking for leverage on Leonora, Christian learns from one of her old friends from school that she used to have a boyfriend named Mike, who mysteriously fell off a cliff to his death one night at an outdoor party.

Realizing that he must have run over another woman, a shocked Christian feigns that he has broken up with Xenia and decided to stay with Leonora.

At a Sankt Hans celebration later that evening, Christian eagerly encourages his friend Kim to help light the bonfire early.

As the police commissioner leaves, Christian and Leonora watch from afar as the fire consumes Xenia's body.

It is revealed that the police commissioner has been telling his daughter the story before her wedding as a cautionary tale about marriage.
