Legend has it that gold and silver relics lie buried within the mines once owned by King Solomon. These artefacts, described as priceless, are thought to have vanished over centuries, hidden away from the world. The notion of such hidden wealth has long captivated treasure hunters, feeding countless rumours about the secret chambers beneath the ancient kingdom. Driven by the lure of the wealth, Rob and Stefan embark on an expedition to uncover the lost treasure. Their search takes them into the depths of the mysterious shafts, hoping to bring the ancient riches back to the surface. As they navigate the tunnels, the duo remains focused on locating the legendary cache that many believe still rests untouched within Solomon's forgotten mines.

Hidden beneath the bustling streets of Naples, a silent menace is gathering. Far below the city’s dense population, an enormous super‑volcano is believed to be approaching a critical threshold, and experts caution that it could erupt with little warning. Should this happen, the ensuing explosion would unleash a cataclysmic blast capable of wiping out the surrounding landscape, overwhelming local infrastructure and threatening the lives of millions of residents. The mere possibility of such a massive geological upheaval looming over one of Italy’s most crowded urban areas adds a chilling urgency to the already precarious situation, and could trigger far‑reaching environmental consequences.

Emerging hypotheses suggest that the legendary submerged metropolis of Atlantis could've been situated somewhere within the American continents. The programme examines these ideas, focusing on the possibility that the fabled city lies not in the Mediterranean but across the Atlantic, in locations that today form part of the New World. To investigate the claim, Rob and Stefan travel from the crystal‑clear waters surrounding the Bahamas to an ancient archaeological site in Louisiana, gathering clues and scrutinising any material that might support the theory. Their quest centres on uncovering tangible evidence that could link the mythic Atlantis to these American locales.

In an unsettling part of the landscape in the remote region, a cavern behaves in reverse to the seasons: it becomes solidly frozen during the warm months, yet thaws and drips when the cold arrives. This baffling reversal defies normal expectations of temperature and challenges anyone who witnesses it. Elsewhere, a towering sand dune erupts with sudden force, engulfing a young child in a single, terrifying moment. The incident, as swift as it is tragic, draws the attention of Rob and Stefan, who set out with urgency to investigate both the anomalous cave and the dune’s lethal surge, seeking explanations for these uncanny occurrences.

The series makes use of cutting‑edge technology, deploying the latest scientific equipment and modern surveying methods, in an attempt to locate the submerged remains of an infamous pirate city that sank beneath the sea. This high‑tech approach combines precision data collection with sophisticated analysis to chart the hidden landscape beneath the water. By harnessing these tools, the team hopes not only to uncover the exact spot where the lost settlement rests on the ocean floor, but also to discover whether any of the treasure it carried remains concealed there, offering a glimpse into a long‑forgotten chapter of maritime history. Should the investigation succeed, it could pinpoint the city's coordinates and any valuables still lying undisturbed in the surrounding sediments.
