Less of an S/M tape (the beatings are very mild), and more of a "tie the pretty girl up and watch her squeal and squirm" sort of tape. But as that, it succeeds. Basically, a dentist and her assistant kidnap their female patients and store them in an elaborate dungeon apparently attached to the dental office (one wonders about zoning violations). The bondage is simple but effective, and the girls all shriek fetchingly through their gags. The lighting and camera work are much better than average, and the dental office scenes appear to actually have been shot in one.
