They came from outer space following inside strange radioactive clouds.
The Crawling Eyes come down from the Swiss Alps and terrorizes the earth. The Eyes hide in the fog-shrouded cloud of mist and kills its victims by decapitation. The best darn giant killer eyeball from space movie ever.
After several molotov cocktails from the scientists, the UN Peacekeeping Force arrives and firebombs the tentacled eyeballs out of existence.
