Paris, 1940. The Nazis have descended on Paris and the Occupation has begun. Businesses across the city have shuttered, but the legendary Ritz Hotel remains open, its dazzling lights still burning bright on the Place Vendôme. When it becomes the favorite watering hole of the occupying forces, its barman, Frank Meier, is forced to adapt to a new clientele. But Frank has a secret: he is Jewish. Tensions rise as the war progresses, but Frank refuses to leave his post behind the bar. Unbeknownst to the Nazi officers he serves night after night, Frank forms precarious alliances with unlikely accomplices in order to save other Jewish families in the city and keep his loved ones alive.
