Nicole Molino (Catherine Spaak) and Nicola Molino (Gianni Garko) are not related to one another. In fact, they don't even know each other until both are inadvertently assigned the same hotel room on the island of Ischi...展开a. Nicole isn't interested in any hanky-panky, so Nicola promises to keep his hands to himself. Though this is an Italian picture, the storyline adheres strictly to tried-and-true Hollywood formula, and Nicole and Nicola fall in love. 18 in the Sun was released in the US under the infantile title Beach Party Italian Style; its original Italian title was Diciottenni al Sole.
