A paean to the sexual underground of New York, circa 1970-85, this engrossing documentary brings together four of its most colorful protagonists for a look back in time, an assessment of where we are today. . . and one very wild farewell party. Our guide to the gritty action is Michele Capozzi, urban explorer and self-titled pornologist, who brings together Neville Chambers, founder of the infamous porn-producing F**k Factory; Lenny Waller, long-time front-man of the meat-packing district's now-defunct Hellfire Club and renowned pornstar/mistress/shaman, Porsche Lynn.
