Raw Wind in Eden (1958)

On a small Mediterranean island live Costanza, her father Urbano, and beachcomber Moore, whom she plans to marry. Into this Eden come two plane crash survivors, supermodel Laura and her playboy friend Wally. The shapely, worldly Laura becomes a bad influence, especially when triangles start to develop. But beyond this, little mysteries lead Laura and Wally to wonder what's going on and who Moore really is.
