Ida moves away from home to study psychology at the University of Oslo. She is worried about most things in life, but her greatest fear is that an act of terror will take place. And when she meets Aksel, a lone wolf who is repeating high-school classes to get into the university and spends his time on dark incels (involuntary celibates) forums on the internet, she starts to think he's a potential school shooter. She tries to squelch the terror-related thoughts, but the more she learns about him, the greater the fear gets. Gradually she realizes that she needs to do something drastic to stop her escalating fear, but how far is she willing to go to save Aksel?
