Way overlong, this late entry in the hit series redeems itself via a surprise ending that was well-conceived.
Instead of the series' core subject matter of incest, this edition deals with BDSM, constituting the secret life style of heroine Penny Flame's missing sister, played (strictly in flashback) by voluptuous Richelle Ryan.
Penny goes looking for sis after she never returns her phone calls and finds herself entering a perverse world, only to suffer when she discovers her sister's secret life.
With many a flashback, story is structured as a mystery thriller, but with very few characters as potential suspects. This self-imposed limitation turns out to be a plus when the final reel's twists and turns unfold.
A large cast of beautiful femmes gives the fans their fill, though only a couple of them (Penny and Richelle) have acting roles, and Richelle gets no dialog at all. Hard-working Adult talent Evan Stone and Steven St. Croix are the only significant male protagonists.
