Will secrets buried in an ancient cave rewrite the story of a desperate time? Nearly 2,000 years ago, a dark, inhospitable cave located in a canyon near the Dead Sea was a secret refuge for Jewish refugees fleeing for their lives from the oppressive rule of the Roman Empire. In 1960, archaeologists discovered dramatic letters written by Bar-Kokhba, the heroic Jewish rebel who led a guerrilla uprising against the Romans. Could the cave conceal more historical treasure from that desperate time? Armed with high-tech equipment, a new team led by archaeologist Richard Freund returns to explore a place that has intrigued the experts for decades. With the help of ingeniously improvised devices, they unearth long-lost artifacts and relics that provide tantalizing clues to turbulent times of messianic fervor, oppression, and revolt. The team's discoveries lead Freund to a radical new theory that he hopes will rewrite Holy Land history--could the treasure concealed in the cave be a long-lost relic of the Great Temple in Jerusalem destroyed by the Romans? Join NOVA for a fascinating detective story that will immerse you in the strong currents of archaeological controversy.
