good use (his own) in his kinky household retinue, presided over by a hunchback henchman named Riff Rail (Richard O'Brien) and his incestuous sister Magenta (Patricia Quinn), and assisted by a tap dancing group-in-residence, Columbia (Little Nell)

Agape in this world of science fiction and fantasy, Brad and Janet don't know what next to expect, when the disastrous result of a previous experiment, an oafish biker named Eddie (Meatloaf), plows through the laboratory wall, wailing on a saxophone. Frank puts a permanent end to this musical interruption without thinking twice until the old professor Brad and Janet had set out to visit, Dr. Scott (Jonathan Adams), turns up at the castle in search of his missing nephew, the juvenile delinquent Eddie. He knows that Frank N Furter is an alien, a spy from another galaxy, and sets out to turn him in, but Frank moves too fast, seducing first Janet, then Brad into his lascivious clutches. Overwhelmed by a newfound libido, Janet hotly attacks the stud Rocky Horror while Brad is under the covers with Frank.

Before Dr. Scott can bring justice and morality into this topsy-turvy Transylvania orgy, Frank N Furter has turned his captives into stone, in preparation for a new "experiment"-an all drag revue-when Riff Raff and Magenta reappear in Transylvanian space togs to wrest control of the mission from Frank N Furter, whose lifestyle is too extreme even for his fellow space travelers. When his lavish histrionic claims of chauvinism fail to soften up Rift Half and Magenta, Frank N Furter tries to escape, only to be gunned down by their powerful ray-guns. Rocky rushes to save his creator but he, too, is blasted to outer space by the militants.

Brad, Janet and Dr. Scott are left in a fog, incapable of readjusting to the normalcy of the life they've left behind in Denton, now that they've tasted the forbidden fruits of the Time Warp.
