Frederick (Nikolaj Lie Kaas) is the principal of a private school, where his wife Mia (Trine Dyrholm) and son Nicholas (Sofus Rønnov) work and study. One day, Frederick was in a traffic accident while driving. After the doctor examined him, he told Frederick that he had a benign tumor in his brain, which compressed his nerves, causing Frederick's behavior to be sometimes out of control. Afterwards, Frederick was charged with embezzlement, and his defense lawyer decided to make a fuss about the tumor. At the same time, Mia also discovered that Frederick had a lover all along. Is his greed and infidelity really because of the tumor in his head?
