A hostile alien wreaks havoc on the cast and crew of an adult movie.
I think the plot of this film more or less explains why it is such a great horror comedy. Ron Jeremy is taken over by an alien, his penis detaches itself... and then it starts killing people. I guess you could screw this up, but they did not.
The film revolves around jokes -- dozens and dozens of jokes. You might think after two or three penis jokes it would get stale, but it never really does. Combined with a fair amount of gore and just a hint of sex, it keeps your attention and your laughter throughout. (For a film about a bunch of born stars, the nudity is very tame -- only one person is even partially naked, and then only for a minute.)
Oh, and Charles Napier. Wow. A serious actor, with plenty of solid credits behind him... and he appears in a film where he not only fights a penis, but delivers one of the greatest monologue ever spoken about aliens in Vietnam. Priceless. This speech alone is worth the view.
