Defending my father's house

Remember, Petra. The first country Hitler invaded was ours.
World War II rages, but life must go on. For Petra Heinrich, this means taking charge of what's left of her family. With her father and older brothers away fighting for their country, she is entrusted with the upkeep of their farm in the sleepy German village. During the day, she struggles with daily chores. At night, she hides in the hayloft while bombs drop all around the farm.
Petra grew up in a devout Christian home, but she has long since hardened her heart to God. However, when she agrees to hide a Jew, Petra's heart slowly softens.
As she starts to trust that things might be improving, the family receives devastating news. Grief-stricken and vulnerable, Petra's courage is tested beyond what she can bear.
Things can't possibly get worse. Or can they?
