It's the psychedelic 70s and social conventions are being challenged. When Catherine Moreland from rural Australia goes on her first trip abroad, a handsome American naval officer sweeps her off her feet and she goes to live in the beautiful Hawaiian Islands with her new husband.
At first, the magic and loveliness of the Islands lead Catherine to believe she is living in paradise. However, as she learns more about the Islands, she begins to discover that paradise has a darker side. And when she meets a mystery man of the sea, as though hit by a tsunami, her life is turned upside down and changed forever.
