Adler spent time in two Jewish ghettos and three concentration camps during World War II. He lost every member of his immediate family to the Holocaust.
Walter Plywaski, who's 86, survived a long string of Nazi camps and eventually found his way to it to Colorado. He tells us his story.
In a new book, Paula Burger writes about escaping the Jewish ghetto and living in the forest with more than 1,000 other people.
