In space, a big jellyfish destroys a satellite. The thing then comes to Earth and uses its twisting tentacles to get everything in its path. Buildings, trucks, and even a bridge get lifted up from the ground by the thing. The thing also has a craving for diamonds. Also involved in this mishmash are some diamond thieves who only want a truck of diamonds and a day to the beach without getting stung. Pretty interesting with imaginative special effects. The American print is terrible,dark, and scratched up. The dubbing is also bad.
