America Unearthed (2012)

Heading to Tucson, Arizona with his son Grant, Wolter is eager to investigate a mysterious cache of crosses, swords and other relics pulled from the desert in the 1920s. One sword has a date--800 AD--written in Latin, which would suggest a group of Europeans was in the American Southwest hundreds of years before Columbus made it to America. Wolter's investigation is particularly important for one man--the grandson of the man who helped discover the items. The investigation could determine whether the artifacts are part of an elaborate hoax or part of a find that could change history.
