Gravity.

Giant globules of molten rock begin floating up out of an ancient glacier in Iceland!

Geophysicist Alex Cave and his friend Okana descend deep into the lava tube of a dormant volcano and discover a 180 million year old alien artifact of incredible power. They are joined by Janice Sloan, a ruthless woman dealing in stolen technology, and John Essex, a millionaire scientist fanatical about conquering outer space and eventually mining the moon.

Sloan and Essex manage to steal the ancient device, but they don't realize its full potential until it begins dragging the International Space Station into the atmosphere and changing the orbit of the moon.
