While assisting an undersea drilling operation, Capt. Crane and the Seaview become locked in a life-and-death struggle with an android, powered by a new source of limitless energy, Subterranium 116.

At the beginning Mr. Omir is shown using his newly discovered element 116, which he dubbed "Subterranium" (presumably because he discovered it while drilling on the ocean floor). At the time of this show there were only 104 known elements. Element 116 would be eventually discovered 35 years later and, after another 10 years of debate, officially named "Livermorium". See more
