When Czechoslovakia relinquishes the Sudetenland to Hitler, the powerful influence of Nazi propaganda sweeps through towns and villages like a sinister vanguard of the Reich's advancing army. A fiercely patriotic secular Jew, Pavel Bauer is helpless to prevent his world from unravelling as first his government, then his business partners, then his neighbours turn their back on his affluent, once-beloved family. Only the Bauers' adoring governess, Marta, sticks by Pavel, his wife, Anneliese, and their little son, Pepik, bound by her deep affection for her employers and friends. But when Marta learns of their impending betrayal at the hands of her lover, Ernst, Pavel's best friend, she is paralyzed by her own fear of discovery - even as the endangered family for whom she cares so deeply struggles with the most difficult decision of their lives.
