Waterworld

Hailed as Kevin Costner's SciFi version of "Heaven's Gate," Waterworld takes place in a future where no-known land exists because the polar ice caps have melted - drowning the world and killing off most of humanity. Now the beraggled remanents of humanity live on floating islands of scavanged wood and dirt is a commodity more precious than gold. Now in one floating wood island, a child has been discovered with a tatoo on his back that is a map leading to the only remaining land above the water. It quickly becomes a race between the good and bad guys as to who will grab the kid and take posession of the only Terra Firma left in the future.
