Living in Jerusalem, Elise Margulies fears for the lives of her husband and daughter every day. Then comes the day when her worst fears come true. Cancer specialist Dr. Jonathan Margulies drives his young daughter home from her ballet recital. His bullet-ridden car is found empty on the side of the road hours later. Elise, in the last stages of a difficult pregnancy, desperately calls her grandmother Leah in America for help and unknowingly revives a decades-old oath. Over five terror and hope-filled days during which ordinary people join the front lines against terrorism, the ties that bind two generations form a powerful alliance against contemporary evil.
