Dementia 4 (2006)

With thousands of Adult credits, Jim Powers has innovated in many genres, and here he provides a form of extreme gonzo content, presented within a narrative format, that is more adventurous than typical porn being ground out today (14 years later).

Though not the classic "Hannah Goes to Hell" which memorably also starred Sin City's great leading lady Hannah Harper, it enters a similar fantasy BDSM territory. We have Lee Stone, as Hannah's hubby, seemingly going crazy after foolishly accepting a Swingers suggestion from his neighbor pal Van Damage.

It starts off as little more than wife-swapping, as Lee reluctantly agrees to sneak in one night to Van's house and service Van's wife (lovely Sasha Knox), while Van reciprocates next door with Lee's spouse Hannah. It all goes awry, and we are treated to Lee's torment as well as a cast of "anything goes" actresses (including Annette Schwarz and Taryn Thomas among the most extreme) performing sex of the kinkiest sort.

One sequence takes place in what looks like the "Immoral Proposal" porn mansion used in the following decade for innumerable video shoots. Powers' elaborate BDSM and fetish stagings show considerable imagination, especially when compared to the subsequent generic BDSM porn from latter-day competition.
