A team of archaeologists discovered a 2,000-year-old scroll in 1952 in a cave near the ruins of an ancient settlement, Qumran. It was classified as a Dead Sea Scroll, but with two distinct differences: it was made of copper, and it did not contain biblical text. Instead, it gave clues to what may be the biggest hoard of treasure ever buried. A team of experts travels to the Holy Land to visit the cave where the metal scroll was discovered, investigate "ghost" inscriptions about the Colosseum in Rome, and determine if the riches were ever found.
