In the first half, historical detective Graham Phillips joined Dave Schrader to present compelling evidence that suggested King Arthur was a real living warrior who led the Britons around the year 500, and that the legendary Camelot, Merlin, Excalibur, and Knights of the Round Table, were all based on facts or real people. Examining overlooked ancient manuscripts in the vaults of the British Library, Phillips concluded that the real life warlord Owain Ddantgwyn, who united British factions to repel an Anglo-Saxon invasion, was actually King Arthur. Owain was known as "the bear" and the word for that in their language was ARTH, he explained.

Based on recent archaeological research, Phillips pointed to the ancient site of Viroconium as being "Camelot," Arthur's fortified capital. The Celtic warriors, circa 500 AD, used to sit in a circle around a cauldron, and because of the seating, they looked at each other as equals. "I think this is where the theme of the Round Table came from," which in medieval times became an actual table with knights sitting round it, he continued. The sword, Excalibur, may relate to the real practice of throwing a great warrior's sword into a sacred lake upon their death, he added.

In the latter half, author and researcher Andrew Collins offered an intriguing hypothesis to the enduring legend of Atlantis. He argued that what Plato recounts is the memory of a major cataclysm at the end of the last Ice Age, when a comet devastated land masses in the Caribbean. Plato knew of the journeys of ancient mariners, who visited islands in the far reaches of the Atlantic, and these mariners were told by indigenous people of the catastrophic events from their distant past which tore apart their islands, he explained.

Fragmented parts of a comet entered into the lower atmosphere around 10,800 BC, Collins estimated, devastating the North American continent, and areas in the Atlantic ocean, with fires, super tsunamis, and great floods. Rather than the destruction happening within a short time frame, Collins believes it took place over a period of several hundred years. "All of the evidence suggests that Cuba is the main location of Atlantis," and was once part of a greater land mass connected to the Bahamas, he cited. There are sunken ruins off the coasts of both Cuba and the Bahamas, ancient complexes spanning more than 10 acres that indicate a lost civilization, urban development and planned road systems, he reported.
