在这部比基尼女郎爱情/冒险片中,在这部愚蠢的喜剧中，漂亮女孩玛丽娜和负责看管灯塔的父亲同住在海边。一天，玛丽娜遇上两个在岸边搜寻宝藏的小伙子，并对其中一个迷恋不已。很快两人间萌发出爱意……本片是碧姬·芭铎最早的出演主角的影片，拍摄于1952年，本片除了在法国外，很少在其它国家上映，直到5年后《上帝创造女人》将碧姬·芭铎捧成了国际明星后才得以在英美等地上映。
When a 25-year old Parisian student, Gérard Morere, hears a lecture about a treasure Troilus lost at sea after the Peloponnesian War, he thinks he knows where it is, thanks to a discovery he made five years before when diving near the island of Levezzi. He gets friends and an innkeeper to invest in his dream, enough to get him to Tangiers where he convinces a cigarette smuggler, Erick, to take him to the island. There he finds Manina, the light-keeper's daughter, 18 and beautiful and pure. Erick thinks Gérard may have conned him, but Gérard's belief in the treasure compels patience. Dives by day and romance at night. Can Gérard's romantic ideas survive in the harsh rocks of Levezzi?
