The movie, a sequel to The Blue Lagoon (1980), was made and first released about eleven years after that picture, but the film has often been considered "virtually a remake of the 1980 version" as Halliwells have noted.
The film's opening prologue states: "The South Pacific Ocean 1897. Fifteen years before our story begins, two children were shipwrecked on an uncharted island. The little boy and girl grew up alone in this lost paradise. As man and woman, they discovered a pure and natural love. In time, a child was born. But in a tragic accident, they were driven out to sea away from their island. Drifting for days, they believed that their lives and the life of their baby were at an end. Then a passing vessel drew near . . . ".
