A group of archeology students and their professor labor carefully to discover the remnants of a fourteenth century castle in the middle of France’s gorgeous and historically rich Dordogne Valley. The project is the culmination of a life-long dream for Professor Edward Johnston. Johnston has made significant progress in unearthing not only La Roque Castle, but also a monastery and structures from the surrounding village of Castlegard, with the help of Assistant Professor Andre Marek, his son Chris, and students Kate Ericson, David Stern, and François Dontelle.
However, things are about to go awry.
Professor Johnston goes to ITC headquarters in New Mexico to find answers about the dig’s donor, International Technology Corporation (ITC), and the man who manages it, Robert Doniger, and while he’s gone, his pupils discover a chamber that has been shut for over 600 years. Marek and Kate descend into the shaky room, where they find two unexpected discoveries: a bifocal lens, which couldn’t have been manufactured before the chamber was shut, and, much more fascinating, a scribbled cry for help from Professor Johnston dated April 2, 1357…
The students are determined to unravel the riddle and travel to ITC headquarters, where they are astounded to discover about Doniger’s new invention – a machine that can broadcast three-dimensional objects through space. Although Doniger intended for the invention to modernize transportation, he mistakenly opened a wormhole that led straight to the fourteenth century, trapping Professor Johnston, who insisted on witnessing the discovery firsthand, in a violent French vs. English feudal battle. Can Johnston’s devoted students survive one of history’s bloodiest battles and return to the twenty-first century alive?
