A fatal accident. Karen, a young mathematics teacher, feels guilty although she isn't.
Seeking forgiveness, she starts a self-destructive relationship with the brother of dead Miriam - one of her students, Lukas.
Guilt as a feeling and not as a judicial resolution - this is the beginning of the journey of our protagonist, who apparently had a well-structured and safe life. However, this time there is an unresolved equation. Karen no longer sees meaning in mathematics - Lukas experiences the same with his parents' religious belief. There is anxiety and inability to talk about one's own feelings and yearnings.

Instinctively, Karen starts a relationship with her 15-year-old student who thinks that she is guilty. The film shows relentlessly how both learn to deal with their anxieties, their mourning and their anger. At the end of the story, two people come together again in a completely new way and experience intensive closeness and warmth again after a long time. Something very unique has evolved between the two of them, something which will last forever even when they have to part again.

We live in a society that wants to control everything. Therefore, there is seldom the necessary space for grief to develop. This extreme character drama asks questions about how to deal with death. It shows that forgiveness often has to go a difficult way and that the longing for it becomes visible in the abyss of the people.
