In 1945 on the outskirts of Salzburg, victorious American soldiers capture a train filled with unspeakable riches: piles of fine gold watches; mountains of fur coats; crates filled with wedding rings, silver picture frames, family heirlooms, and Shabbat candlesticks passed down through generations. Jack Wiseman, a tough, smart New York Jew, is the lieutenant charged with guarding this treasure -- a responsibility that grows more complicated when he meets Ilona, a fierce, beautiful Hungarian who has lost everything in the ravages of the Holocaust. Seventy years later, amid the shadowy world of art dealers who profit off the sins of previous generations, Jack gives a necklace to his granddaughter, Natalie Stein, and charges her with searching for an unknown woman -- a woman whose portrait and fate come to haunt Natalie, a woman whose secret may help Natalie to understand the guilt her grandfather will take to his grave.
