On an April day in 1937, the sky opens and fire rains down upon the small Spanish town of Guernica. Seventeen-year-old Sibi and her family is caught up in the horror. Griff, an American military attacȟ, pulls Sibi from the wreckage, and it's only the first time he saves her life in a span of hours. When Germany claims no involvement in the attack, insisting the Spanish Republic was responsible, Griff guides Sibi to lie to Nazi officials.
