Das Adlon. Eine Familiensaga -  It's where commerce and politics meet money and glamour, and where sin can count on discretion – the Hotel Adlon in Berlin, one of the grandest of the world's grand hotels.

A new period of sorrow and suffering begins, as Sonja steadfastly guides the Adlon through the war and post-war years, while burning to know what has happened to Julian and her daughter...
