16-year old Anastasia and her adopted brother Damir live on a Greek island with their pervy grandfather. She dreams about having a large antique bathtub and he dreams about running a sea-side resort. They begin to fall for each other.
Set on a lush Greek island, the story concerns a sister (Bo Derek) and brother (Peter Hooten), who return home after years abroad. Falling under the island's erotic spell, the girl and boy discover that their love goes beyond filial. The incestuous nature of the story evaporates when it is discovered that the two aren't actually related after all.
