In the heart of the beautiful and historically rich Dordogne Valley of France, a team of archeology students and their professor diligently work to uncover the ruins of a 14th-century castle. For Professor Edward Johnston, the project is the culmination of a lifelong dream. Aided by assistant professor Andre Marek, his son Chris and students Kate, Stern and François, Johnston has made major strides in unearthing not only La Roque Castle but also a monastery and structures from the surrounding village of Castlegard. But things are about to go haywire… Suspicious of the dig’s benefactor, International Technology Corporation (ITC) and the man who runs it, Robert Doniger, Professor Johnston heads to ITC headquarters in New Mexico to get some answers, and while he’s away, his students discover a chamber that has been sealed for more than 600 years. Marek and Kate descend into the unstable room, and just before a near disastrous cave-in, they make two startling discoveries — a bifocal lens, which couldn’t have been invented before the chamber was sealed, and even more intriguing, a handwritten plea for help dated April 2, 1357…from Professor Johnston! Determined to solve the mystery, the students head for ITC headquarters, where they are stunned to learn of Doniger’s new invention — a machine that can actually transmit three-dimensional objects through space. Although he meant for the device to revolutionize shipping, Doniger inadvertently opened a wormhole that leads directly to the 14th century, and Professor Johnston, who had insisted on experiencing the discovery himself, is now trapped in a vicious French vs. English feudal war! Can Johnston’s loyal students survive one of the most violent battles in world history… and make it back to the 21st century alive?

In 1412, a young girl called Jeanne is born in Domrémy, France. The times are hard: The Hunderd Years war with England has been going on since 1337, English knights and soldiers roam the country. Jeanne develops into a very religious young woman, she confesses several times a day. At the age of 13, she has her first vision and finds a sword. When coming home with it, she finds the English leveling her home town. Years after that, in 1428, she knows her mission is to be ridding France of the English and so sets out to meet Charles, the Dauphin. In his desperate military situation, he welcomes all help and gives the maiden a chance to prove her divine mission. After the successful liberation of Orléans and Reims, the Dauphin can be crowned traditionally in the cathedral of Reims - and does not need her anymore, since his wishes are satisfied. Jeanne d’Arc gets set up in his trap and is imprisoned by the Burgundians. In a trial against her under English law, she can’t be forced to tell about her divine visions she has had continuously since childhood. Being condemned of witchcraft and being considered as relapsed heretic, she is sentenced to death. Jeanne d’Arc is burnt alive in the marketplace of Rouen on May 30th, 1431, at only 19 years of age.
