Angel Brown arrives in London in a quest to obtain more information about the death of her twin brother, Dan. She wants to talk with Major Zachary Talbot, the pilot of the B-17 bomber her brother had perished on. She finds out the Major is a very reserved person who keeps to himself. Angel decides to stay and assist at the local orphanage at least until she gets answers to her questions. Amidst the horrors of round-the-clock bombing, air-raids, black-outs, food and gas shortages, these two Americans are drawn together as an unseen EVIL stalks them.
