In 1940, Germany seizes control of Guernsey without a fight – but not without resistance. Innocent young teacher Catherine is forced to house a German officer. Shrewd waitress Betty seeks to elude the persistent Nazi determined to conquer her. And courageous nurse Helen cares for her patients – both British and German – while hiding a British spy in her seaside cottage.
Their fight against the injustices being enacted on their island home brings the women, the spy, and their enemies together in one night that will change all of their lives forever. Though none of them could foresee that the battle they fought that night would reach across time to 1997, when the tragic fallout ensnares Helen once more.
