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 two and a half years. The children flee to another part of Palm Tree Island. Over a period of five years, they grow up and fall in love. 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, the young couple live in island bliss until they are unexpectedly expelled by the ocean tide from their tropical Eden.
