<p>An English transvestite by the name of Dr. Frank n Furter, who occasionally poses as a Minister, receives two people into his castle late into the night: a man and a woman; they are engaged to wed. </p>
<p>After rousing bouts of experimental dance music, the transvestite, accompanied by the soon-to-be newlyweds, his assistant Riff Raff and Riff Raff's sister Maroon, take a trip into the lab where he is creating a monster by the name of Rocky. Rocky comes to life and the Doctor makes it clear that his use of the monster is as a sexual companion. </p>
<p>However, before the monster and his creator are able to get down to business, a strange young delivery boy bursts into the room and loudly breaks into song and dance. This song was apparently his last, as shortly after he is finished, the crazed Doctor takes him into the freezer and offs him. The monster and his creator venture off into the Doctor's bedroom where they can finally be alone, and the man and woman visitors are escorted to their rooms.</p>
<p>In the middle of the night, the transvestite visits both visitor's rooms pretending to be his or hers significant other, and mayhem ensues. In the midst of this chaos, the visiting women sleeps with the monster the doctor had created. Not soon after the Doctor finds out of this infidelity, another Doctor (who happens to be an ex-professor of the visiting man) shows up intending to prove that the transvestite is actually an alien from the planet Transsexual. </p>
<p>Soon after all the visiting parties and the hosts of the house had sat down to dinner, the Doctor turns the visitors into statues. As statues, he transports them to a grand stage in the castle and dresses them in the same showgirl costumes (yes, even the men). They are turned back to normal, and the two Doctors, the visiting couple, and the monster named Rocky begin to perform a dance number.</p>
<p>After this peculiar can-can like dance, Riff Raff and his sister barge into the room wearing peculiar extraterrestrial costumes and wielding laser guns pronouncing to the Doctor Frank n Furter that they intend to return to the planet of Transsexual. The Doctor is so overwhelmed with happiness that he breaks into song, but is killed by Riff Raff as soon as he finishes. Rocky is also killed, and the visiting couple and their Doctor are able to escape right before the castle they were staying in lifts off the ground and rockets into the sky.</p>
<p>And all this, because the visiting couple's tire blew out.</p>
