A criminologist narrates the tale of the newly engaged and innocent couple, Brad Majors and Janet Weiss, who find themselves lost and with a flat tire on a cold and rainy late November evening, near a town called Denton in 1974. Seeking a telephone, the couple walks to a nearby castle where they discover a group of strange and outlandish people who are holding an Annual Transylvanian Convention. They are soon swept into the world of Dr. Frank-N-Furter, a self-proclaimed "sweet transvestite from Transsexual, Transylvania". The ensemble of convention attendees also includes servants Riff Raff, his sister Magenta, and a groupie named Columbia.
