L'isola inaccessibile

This story continues immediatelly after previous one where Furio defeated master of the mystery from China. Furio crashes with a plane on the shores of a Pacific island surrounded by a coral reef. Here the unexpected happens: on the island lives a colony of white descendants of ancient pirates who, thrown on the island by a storm four hundred years earlier, could not get out of it again because of the coral reef. The pirates are fighting against the native Kanaks (indigenous Melanesian inhabitants of New Caledonia) who take Furio prisoner, to whom the tribal chief tells the story.
