Janet Weiss, A Heroine (Susan Sarandon)’s Timeline and Summary

Janet catches the bouquet at her friend's wedding and is immediately proposed to by Brad. We had no idea that ritual actually worked.
That night, they get a flat tire and look for help in a nearby creepy castle. This will go well.
They stumble upon a party of the "Annual Transylvanian Convention" led by a gender-bending mad scientist named Frank.
Frank orders Brad and Janet be stripped to their underwear and brought to his lab.
In the lab, Janet watches as Frank brings his creation, a musclebound hunk named Rocky, to life.
After seeing Rocky flex a few times, Janet (and everyone else) officially becomes a "muscle fan."
Forced to spend the night, Janet's seduced by Frank.
Via a hidden camera, she sees that Brad, too, has been seduced by Frank.
Jealous, Janet finds Rocky and gets him to touch-a touch-a touch-a touch her in places we assume Brad never has.
Janet and Rocky are caught by Brad, but they are turned to statues before they have time to hash out their feelings over their mutual betrayals.
Janet is softened up to perform in a racy burlesque number.
When Frank is killed at the end of his performance, Janet learns that Frank and his pals are really aliens.
They boot Janet from the house before the house itself blasts off into outer space.
Janet, Brad, and their mentor, Dr. Scott, writhe in the dirt. Their lives will never be the same. And neither will ours.
