Plot
When two archeologic adversaries find an ancient set of hieroglyphics in a prehistoric cave, the ramifications prove to be catastrophic. For within these ancient manuscripts lie information that could awaken 'Yonggary', the largest dinosaur ever discovered by man. A greedy, fame seeking archeologist named Professor CAMPBELL steals and decodes enough information to lead him to the burial site of the prehistoric fossil. As Holly, his assistant, becomes more disgruntled with CAMPBELL's desire to continue the dig, Dr. Wendell HUGHES, a noted Paleontologist who has been missing for the last two years, suddenly appears at the excavation. He begs CAMPBELL to stop and rebury the fossil before the monster awakens, only to be thrown out of the site. Teaming with Dr. HUGHES, Holly attempts to decode part of the ancient hieroglyphics. When Dr. Hughes and Holly return to the excavation to stop CAMPBELL, it is too late: a great green beam of light emitting from a strange spacecraft above the earth strikes the fossil and resurrects Yonggary. With nowhere to turn, Dr. HUGHES and Holly resume deciphering the remaining part of the code with the hopes that it will reveal a way to stop Yonggary from destroying the world.
