Based on a true story. At the end of the 1930s, before the Americans entered the war, the streets of New York are in a tumult. Anti-Semitic and racist groups are eager for the sympathy of the masses, and German nationalists celebrate Hitler as the man of the hour. Josef Klein, himself an immigrant from Germany, lives relatively untouched by all this. His great passion is the amateur radio. But Josef's technical abilities as a radio operator attract the attention of influential men. Josef accepts the offer to work as a radio operator without fully understanding for whom he will be working. When he finally interprets the events correctly, it is too late and he is already a little cog in the big wheel of the espionage network of the German defense. After detention and internment on Ellis Island, Josef is deported to Germany. His fateful path leads him to his brother Carl's family, a family father and soap merchant in Neuss; and finally to South America, where Josef becomes José. But how long can you really hide from your own past, before it catches up with you?
