Episode One will explore the dynamic and shifting relationship America had with her new immigrants in the 20th century. World war tore apart families; and sundered the fabric of many lives; but America beckoned and millions came. Yet, America was an ambivalent host. At its best, a place of refuge and salvation, as for film director Mike Nichols whose entire family escaped Nazi Germany. At its worst, a country that would imprison two generations of Japanese Americans, like the ancestors of Olympic gold medalist Kristi Yamaguchi. Along the way, we'll discover the buoyant American optimism that shaped chance - as in a single encounter that changed cellist Yo-Yo Ma's life forever - to pave the road to success.
