Les chattes du collège

There are 2 versions of this movie that you might encounter in the US.

It was originally released in the US with the name changed from Schulmadchen Report 6 Teil to Campus Pussycats. This version was then dubbed into something resembling English, and then all the Full nudity was removed, while the TnA was left in.

The other version is Schoolgirl Report Volume #6, which has removable English subtitles, and all of the full nudity remains.

Most people who watch movies like this don't really care about the plot or acting, if you are looking for TnA it has plenty. If you like full frontal nudity featuring women from the 1970s, you want to avoid Campus Pussycats.
