Archivists slowly trawling through reams of Nazi documents learn of the potential existence of another final German wonder weapon. A modified V2 rocket with a new type of fuel that increased its potential range to include the United States, chillingly codenamed 'Eagle'.

Gunn and Laszlo are reluctantly tasked to find the answers, a seemingly innocent car crash switches their focus in a different direction as they begin to uncover something far more sinister, so frightening that it finally makes the intelligence community sit up and take note.
