When an entire office building is sucked under the earth's surface, the Skysurfers investigate and discover it was no ordinary earthquake that split open the ground, but rather giant monster worms from a lost underground civilization of humans who are raiding the "surface dwellers" in an attempt to take over the upper world. What follows is a deadly journey below the earth's surface as the Skysurfers attempt to stop these under-world raiders and their giant worms before Cybron joins forces with them.
