In the midst of World War II, postman Ludwig Fuchs writes a letter to his former school friend Field Marshal Hermann Göring, urging him to work for peace. He is declared mentally incompetent. After the war, he struggles to shake off the stigma of alleged mental illness. Göring is executed. Fuchs forces the court to examine him: he vandalizes the lobby of Post Office 122 in Munich and is rehabilitated (with full salary compensation for lost years).
