Producer Jim Newman joins a team of divers to explore a cave and underground lake in a remote area of Oregon. They are searching for mysterious creatures that thrive in the eternal night and for the cave’s outlet and main water source. The expedition, with its team of surface support people and equipment, takes on the feel of a space launch.
