A definitive and spellbinding record of the legendary Antarctic expedition. Trapped in the Antarctic ice over 1,000 miles from civilization, polar explorer Sir Ernest Shackleton and his 28 brave crewmembers endured nearly 15 harrowing months stranded on the ice pack in a daring and courageous adventure that became the greatest survival story of all time.

Who were the first Americans and where did they come from? The conventional view is that they arrived here around 13,500 years ago, but startling new archaeological discoveries suggest it may have been long before that. And experts are testing contentious theories regarding how they got here, including the idea of a dangerous canoe-born voyage from Asia down the west coat of the Americas, or even across the Atlantic from Europe.

The movie “The Great Escape,” starring Steve McQueen, was based on fact – on the most daring and technically ingenious prison escape of World War II. The location was a remote, high-security internment camp for Allied airmen. Known as Stalag Luft III, the camp was at Sagan in present-day Poland. The escape emerged from a stunningly ambitious plan: Allied POWs set out to dig three tunnels more than three hundred feet long and thirty feet below ground, which they nicknamed ‘Tom,’ ‘Dick,’ and ‘Harry,’ so that if the Germans discovered one tunnel there would still be a fallback. NOVA follows a team of archaeologists on a hunt for the single surviving tunnel, ‘Dick,’ that the Germans never found. Accompanying the team was a group of three of the original escapers, who returned to the scene of their daring escapade for the first time in sixty years. The film shows the ingenious methods and devices improvised by the prisoners: how they surveyed the tunnels, disguised the entrance traps, and engineered an amazing air pump and railway system, all from materials scavenged from the camp. But when the time for the breakout came, the thrill of the escape would take an unexpected and tragic turn.

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.

There are few more tantalizing or notorious historical documents than the Vinland map. A faded, yellowing scrap of parchment bearing a faint tracery of lines, the map apparently shows the eastern seaboard of North America-yet it was drawn at least half a century before Columbus reached the New World. It seems to present unshakeable proof that the Vikings were the real discoverers of the Americas. But for 40 years, a bitter debate over its authenticity has raged among cartographers, historians, and scientists. Despite chemical analysis and radiocarbon tests, the case remained unresolved. Now, in an exclusive investigation, NOVA presents fresh evidence confirming that the map was probably one of the cleverest forgeries of all time, and probes who might have wanted to carry out the deception. In this enthralling cartographic detective story, NOVA pursues a trail from Scandinavia to Austria, Switzerland, London, and the U.S.
