A man with spiritualist powers is told by his mentor that a demonic entity is returning to destroy his daughter's soul, and that he should take drastic measures to prevent this from happening.

Reporter Emanuelle (Laura Gemser) is doing a story on the white slave trade and tracks everything to a gangster living in Africa. Not happy stopping there, Emanuelle comes back to America and begins working undercover. This is probably the best of the D'Amato/Gemser Emanuelle movies but that's not saying too much. Unlike the other films in the series this one here at least manages to be entertaining without having to have a woman jerk off a horse as was seen in Emanuelle in America. This film here has a pretty interesting story and it moves along without too many boring spots. Needless to say there's a lot of sex scenes with Gemser taking on various men and women and these here are without a doubt the best scenes. D'Amato makes most of these very erotic, which is another thing missing from others in the series. I wouldn't say Gemser gives a good performance but she is comfortable in the role and you can't complain about seeing her naked throughout the film. The scenes in Africa are well shot and it's nice seeing some of the wildlife. Some of the American scenes were lifted from Emanuelle and the Last Cannibals but this just adds to some of the cheap fun. Original title: Via della prostituzione, La.
