Deep beneath the Pacific lie fields of manganese nodules rich in nickel, cobalt, and copper, minerals the world's battery and electronics industries want badly. Reporter Michael Stocks and his cameraman spend weeks aboard the research vessel Island Pride, filming scientists as they monitor a giant harvesting machine designed to strip these nodules from the seafloor. The crew includes researchers who disagree with each other about whether the operation is safe, and their arguments on deck carry as much weight as any narration. Footage from remotely operated cameras shows the machine churning through sediment thousands of meters down, raising sediment plumes that could smother creatures scientists have barely begun to catalog. The film sets this expedition against the larger pattern of extraction on land and at sea, from beach sand dredging to depleted fishing grounds, asking whether the deep ocean is the next resource frontier or a fragile system nobody understands well enough to disturb. It stays with the ship and the data rather than settling the question for the viewer.
