A documentary following a team of biologists and geologists 1 1/2 miles below the ocean surface where they discover worlds of life around thermal vents which are supported by bacteria that convert chemicals into organic matter. This landmark dive confirmed aspects of the theory of plate tectonics and yielded important biological discoveries. The underwater footage was filmed from the Alvin submersible, which traveled aboard the mothership Lulu. Hydrothermal vents are one of the greatest discoveries of the twentieth century and are theorized to be the originators of life on earth.
