A dinosaur is discovered in Siberia frozen in ice. The Daily Planet learns it may still be alive after it is brought to be displayed in America. A can of oil falls in the generator while Lois is getting a tour and the ice melts, letting the dinosaur out. It destroys the building, trapping Lois. Clark changes and sets about rescuing Lois and fixing the path of destruction left by the dinosaur, finally tying it up with thick metal cords from a bridge.
