Deep beneath the waves lies a geologically violent and alien landscape that remains one of the last great unexplored frontiers on Earth. In this documentary, we embark on a treacherous 7-mile journey from the sunlit surface to the crushing depths of the Mariana Trench, revealing a world of 100,000 volcanoes, underwater lakes that defy physics, and the "Lost City" of white towers fueled by chemical heat. As we follow the seafloor’s epic journey from the volcanic mid-ocean ridges to the deadly subduction zones, we discover how these hidden forces create the very land we live on, and possess the power to destroy it in an instant.
