Who Do You Think You Are? (2004) : 14x10

Ruby Wax's Jewish parents fled Vienna and the Nazis for America in 1938. 'They took the war with them and brought it to our kitchen,' says the comedian and mental-health campaigner at the start of this remarkable episode. They raised their only daughter in a dramatically dysfunctional household - Ruby's father was volatile and her mother 'hysterical... screaming in the street.' Ruby wonders if her own mental illness had its origins in her upbringing and the trauma her parents went through, or whether it is in her family's genes. Ruby journeys to central Europe, where she learns about her parents' flight and the distressing fate of family who remained in Vienna during the war, and she makes a startling discovery about her great-aunt and great-grandmother, which is both harrowing and surprisingly affirming.
