A story of German-Americans in Yorkville, and Jews in the Bronx, which reduces racial and national symptomology to terms of Gefullte Fisch and Wiener Schnitzel, Oi Weh and Ach. The sadness in Lexington Avenue iss when Eric Schiller, more American than German, defies his father, more German than American, and falls in love with Mary Goldman. Both make an emotional exodus from the homes of their parents to marry, and three years later Mary dies, in giving birth to a son whom Eric abandons to his parents as he joins up-and dies in the First World War. The baby, named Christian, is brought up in ignorance of his mother's ancestry, joins the Bund, and in a riot against a Shul congregation picnic, attacks his own grandparents. Later informed of their identity, he has a sudden change of heart and is off to the war against Hitler after a respectful adieu to the Goldmans in the Bronx...An oversimplified approach to types and tongues which reaches some points of unbelievable behavior, both uptown and downtown, this has little of the romantic appeal of earlier successes.
