When abducted because of his secret, a clumsy teenager with acidic semen must save himself and a porn actress from the set and crew of a deranged snuff film director.

The funniest thing about this is "withdrawn".

HA. Puns.

By acidic do you mean like the alien's blood in Alien? Otherwise, it implies and uncomfortable experience for his co star but otherwise no big deal.

If you're trying to create a story about someone out of their depth in the porn world, Orgazmo would be a good reference - I'm not sure how long a withdrawn teenager could believably stay a fish out of water in porn.
