The Blue Lagoon is the story of two cousins, Dicky and Emmeline Lestrange, stranded on a remote island with a beautiful lagoon. As children, they are cared for by Paddy Button, a portly sailor who drinks himself to death after only two and a half years in paradise. Frightened and confused by the man's gruesome corpse, the children flee to another part of Palm Tree Island. Over a period of five years, they grow up and eventually fall in love. Sex and birth are as mysterious to them as death, but they manage to copulate instinctively and conceive a child. The birth is especially remarkable: fifteen-year-old Emmeline, alone in the jungle, loses consciousness and awakes to find a baby boy on the ground near her. Naming the boy Hannah (an example of Stacpoole's penchant for gender reversals), the Lestranges live in familial bliss until they are unexpectedly expelled from their tropical Eden.
