Waterworld

In a future where the polar ice caps have melted and most of Earth is underwater, a mutated mariner fights starvation and outlaw "smokers," and reluctantly helps a woman and a young girl try to find dry land.

The polar ice caps have melted, and the earth is covered by water. The remaining people travel the seas, in search of survival. Several different societies exist. The Mariner falls from his customary and solitary existence into having to care for a woman and a young girl while being pursued by the evil forces of the Deacon.
