All US hardcore versions for home use are missing the Amber Hunt / Robert Kerman (as "R. Bolla") scene. This seems to be for time rather than for content. The missing scene is rather interesting as it further examines Fiona's past. A laser disc edition from the 1980s has the missing scene. The only problem is that the entire disc is the soft core version and the Hunt / Bolla sex is severely edited. Fortunately for movie lovers everywhere, a German distributor (Amor-Video-Club) managed to piece together the complete uncut version.
