The listing, Timeline: They had to travel into the past to save the future. Ultraviolet code only has ended.
While excavating in the Dordogne Valley of France, a scientific research teams new invention, a time travel machine, has inadvertently sent archaeology professor Edward Johnson back to 14th century France.... and has landed him in the middle of the raging Hundred Year War between the French and English. Johnston's only chance for rescue lies in the hands of his own son Chris, his assistant professor Andre Marek and several of his students. The intrepid time travelers must make the same treacherous journey and, with the deadline of only eight hours now ticking away, must navigate through the hostile, war torn territory and retrieve the professor before he's lost to history forever.
