When Nazi forces invaded Holland in 1940 and began rounding up Jews, Corrie ten Boom, her sister Betsie, and their elderly father risked their lives to save as many as possible. A hidden room was secretly built in their home where the oppressed Jews took refuge until a Gestapo raid put an end to their operation. Corrie ten Boom: a Faith Undefeated recounts this unforgettable story for a new generation.
