On a quiet morning on the British coast, a group of fishermen encounters a gigantic and mysterious sea monster. As the locals try to make sense of this phenomenon, they unwittingly release a colossal creature that has been trapped in the depths of the ocean for centuries. This being, a type of prehistoric dinosaur called Gorgo, quickly becomes the epicenter of unimaginable chaos when, in an attempt to take it to London for exhibition as a curiosity, its mother—a even more imposing creature—emerges from the sea, furious and determined to reclaim her offspring.
As the city turns into a battleground between the incredible Gorgo and the unleashed military trying to contain it, the situation escalates to epic levels. Buildings are destroyed and panic spreads among the population as scientists, local leaders, and the military must decide what to do in the face of this threat that defies all logic. The film not only focuses on action and special effects but also touches on themes of exploitation and human greed, questioning the morality of bringing the creature to civilization for personal gain.
With a blend of suspense and social critique, the story explores how humanity often triggers its own destruction when it attempts to dominate what it cannot understand. In the end, the struggle for Gorgo's survival strikes an emotional chord, reminding us that even the most fearsome creatures can evoke empathy.
