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.

For their 'crimes,' Corrie and Betsie were sent to the notorious concentration camp at Ravensbruck, where they suffered relentless cruelty.
