A giant classic of sci-fi action in which a volcanic eruption in the North Atlantic brings a 65-foot prehistoric monster to the surface. The crew of a nearby salvage ship ensnare the monstrous sea creature and put ‘Gorgo’ on public display as the star attraction in a circus in Battersea Park, London. But when a scientist confirms Gorgo is just a baby, his 200-foot-tall mother descends on the capital in order to rescue her kidnapped offspring, destroying everything in her way including London’s iconic landmarks!
