Lisa Kudrow's roots date back to the Holocaust, which means her family connections, like many other Eastern European Jews, have been lost. Her father, Lee, has been trying to solve one of their family's mysteries for almost 60 years. What happened to their family during World War II--and what became of a long-lost cousin who survived it? Lisa is on a mission to find out. Her father grew up impoverished in New York and then worked his way up to become a doctor. Lisa believes by trying to find out what happened to her great-grandmother and distant cousin she can find the answers her father has been searching for--as well as find some of her own.
