What happens when a USAF fighter pilot, on a routine training mission with 3 other F-22 Raptors, suddenly finds himself completely alone in the sky. He manages to land when his digital instruments go crazy - only to find himself on a Royal Flying Corps airfield - in 1916! How does he explain himself, with a supersonic fighter from 100 years in the future, how does he hide it from the Germans, and how does he get back to his own time, with the British girl he has fallen in love with - without her ageing a century!
