The story, narrated by a criminologist, is that of a newly engaged young couple, Brad Majors and Janet Weiss, who find themselves lost and with a flat tire on a cold and rainy night. Seeking a phone with which to call for help, the two knock on the door of a nearby castle, which they find is inhabited by strange and outlandish people who are holding an Annual Transylvanian Convention. They watch, still wet from the rain, as the Transylvanians dance the Time Warp, the film’s signature song.
They are soon swept into the world of Dr. Frank N. Furter, a bizarre and self-proclaimed “sweet transvestite from Transsexual, Transylvania” and his servants, brother and sister Riff-Raff and Magenta, as well as a groupie Columbia and an ensemble of convention attendees.
Frank claims to have discovered the “secret to life itself” and in a scene inspired by the classic Frankenstein movies, his creation Rocky Horror is brought to life. The ensuing celebration is interrupted by Eddie, an ex-delivery boy, who rides out of a deep freeze on a motorcycle and performs a rock-and-roll number. In a jealous rage, Frank corners and slaughters him with an ice axe.
Rocky and the guests are served dinner, which they soon realize has been prepared from Eddie’s remains. Janet runs screaming into Rocky’s arms, and is chased through the halls of the castle by Frank and the rest following behind. Janet, Brad, Dr. Scott, Rocky, and Columbia all meet in Frank’s lab, where Frank captures them with the Medusa Transducer, a machine which transforms them into living statues, and then forces them to perform in a cabaret-style floor show. The performance is interrupted by the appearance of Riff-Raff and Magenta, who stage a coup and announce their plan to return to the planet Transsexual. After explaining to Frank that he is not going back with them, they use a laser to kill him, and in the process also kill Columbia and Rocky. They release the remaining earthlings â€” Brad, Janet and Dr. Scott â€” warning them to get off the property; after they do so, the entire castle takes off into space to return to the planet of Transsexual, in the galaxy of Transylvania.
