A man prospecting for gold in the desert becomes lost and comes across six naked women.The genre being what it is, the hook is beautiful nearly-naked women. This film delivers. Oh boy does it deliver. The topless women show up at about the five-minute mark, and remain on screen for the rest of the film. There isn’t a minute that goes by without bare breasts, and these women are absolutely gorgeous.There are typical of the kind and quality of jokes told throughout the film. In fact, if your family has a liberal attitude about the sight of bare breasts (and occasionally buttocks), this is a great film for kids as well as adults, because these jokes can be appreciated by kids of all ages, and there is nothing (besides the nudity, depending on your values) that is inappropriate for children. This is simply a delightful film.
