James Cameron and Simcha Jacobovici go on an adventure to find the lost city of Atlantis by using Georgeos Díaz-Montexano as story-advisor, Richard Freund and others investigators, and to Greek philosopher Plato as a virtual treasure map.With the objective of evaluating the hypotheses about the existence of Atlantis, the documentary investigates archaeological objects, satellite photographs and seabed related to them.James Cameron instructs a team of professors from several universities in the US, Canada, Israel and New Zealand to assess the most credible hypotheses. The chosen hypotheses were Santorini, Malta, Sardinia and southern Spain and Atlantic. With these data, James Cameron entrusts to Simcha Jacobovici the filming and the direction of the documentary.The investigation begins with the Santorini hypothesis of Charles Pellegrino and continues in Malta, to analyze the hypothesis of Peter Ellul Vincenti, and in Sardinia, to assess the proposal of Robert Ishoy, which end up being discarded.The second part of the documentary begins in the Columns of Hercules, the present Strait of Gibraltar, which is the scenario where the hypothesis developed by the Spanish writer and Story-Avisor of the documentary, Georgeos Díaz-Montexano, and Dr. Richard A Freund. This theory is supported by J. Cameron and Simcha Jacobovici, as the most plausible of all.Finally, the documentary explores the Terceira and Pico islands of the archipelago of the Azores, and concludes considering as more plausible the hypothesis proposed by southwestern Iberia as a central point from which the Atlantic maritime civilization of the Chalcolithic and the Bronze, civilization that generated the legend, to other places of the Atlantic and the Mediterranean.
