The 20th century displaced more people than any before it, wielding nationalism and ideology to inflict unparalleled separation, disappearance and heartbreak on families the world over, and we're still sorting the consequences. Ten years after the death of her father, a Romanian Jew who spent WWII in Paris, filmmaker Pola Rapaport found a curious photo of a boy in his desk in New York. Ten years after that, a letter arrived unexpectedly from Bucharest. "I am taking all my courage when I say that I am actually your brother," wrote Pierre Radulescu-Banu. So begins a brave search for missing family truths in this poignant, poetic depiction of a sibling connection being born across cultures and continents.
