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 in to the university, and spends his time on dark incels (involuntary celibates) forums on the internet, a thought starts to arise in Ida that Aksel is a potential school shooter. Ida attempts to keep the terror related thoughts away, but the more she learns about Aksel, 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?
