Waterworld Synopsis

Imagine a future without dry land. A future where the earth, covered in water, has evolved into a gritty, nautical society held together by determination and ingenuity. The inhabitants of this once-flourishing planet cling to life on incredible floating cities, their existence constantly threatened by Smokers-- bands of marauding pirates who roam the featureless surface of Waterworld.
