Godzilla rampages in Orange County, resisting the attacks of G-Force and the army when suddenly he vanishes into thin air. Professor Mason has teleported the monster out to sea for his own purposes. Dr. Kagaku decides that Mason is responsible for Godzilla's disappearance. Time travel was mason's obsession, like Kagaku's before Godzilla appeared. With Godzilla in place, Mason attacks Pompeii moments before Vesuvius erupts. Mason and a team of raiders stand ready to loot the Roman city in Godzilla's wake.
