 The world is flooded. Civilisation is lost under the sea. The Mariner sails his trimoran over the seas, drinking his own Urine and visits a floating atoll of "Drifters". When they find the Mariner to be a mutant they sentence him to death. Meanwhile, a girl with supposedly a map to get to dry land tattoo-ed on her back, is the objective for an attack by a gang of smokers who attack the atoll.
