A watchmaker like her father, Corrie ten Boom enjoys working with needy children in Haarlem. When the Nazis overrun Holland, Corrie and her family make a fateful decision to assist Jews and Dutch resistance workers. They construct a secret room in Corrie’s bedroom in case of a Gestapo raid. Betrayed by a fellow countryman, the ten Booms go to prison for their 25 “illegal” activities. Four of the family die, while Corrie survives due to a clerical error authorizing her release in December of 1944.
