Seventeen-year-old Franz journeys to Vienna to apprentice at a tobacco shop. There he meets Sigmund Freud, a regular customer, and over time the two very different men form a singular friendship. When Franz falls desperately in love with the music-hall dancer Anezka, he seeks advice from the renowned psychoanalyst, who admits that the female sex is as big a mystery to him as it is to Franz. As political and social conditions in Austria dramatically worsen with the Nazis' arrival in Vienna, Franz, Freud, and Anezka are swept into the maelstrom of events. Each has a big decision to make: to stay or to flee?
