In a bar in Tel Aviv, a German musician signs a drink receipt with 'Adolf Hitler'. The act, as banal as it is outrageous, has serious consequences. He loses his job, his friends, and his girlfriend. Delius takes up the incident, which made headlines in 1997, and asks: What drives someone who does not want to be an anti-Semite to such a lapse? An exciting, slightly maddening narrative about music and love, Berlin and Tel Aviv, German complexes and Italian arias, about rampagers and brass players - a political puzzle with a surprising finale.
