Each Sunday, renowned psychoanalyst Sigmund Freud welcomes his grandchildren into his study for an obligatory audience. When, on one occasion, Sophie is the only grandchild to show, she and her grandfather share tense and awkward moments. Sophie’s troubled home life has left her polite but distraught; Freud is distracted by work and haunted by past trauma. Over time, as their relationship develops, the two Freuds challenge each other’s ideas and debate their country's future, wherein Sophie must choose between a life of devotion to Freud and almost certain destruction before it’s too late. Freud und Freud pits the threat of rising fascism against the powers of intellect, legacy, and family.
