Hunter gets an audition for Oliver Stone but is hesitant when she learns she may have to gain weight to get the part. When she balks, Courtney tells her a real actress would put on the pounds, and Marcy offers to help her beef up. Meanwhile, Dave snags the script and makes copies to auction online.

The show films a lame Halloween fantasy episode in which the characters become vampire slayers. After recovering from an on-set accident, Marcy finally finds her own hot guy when the girls take her out clubbing. Meanwhile, Dave has to find another place to live when Johnny throws him out of the trailer.

Hunter is ecstatic when she talks Rob into hiring her reformed-alcoholic mother Helena for a bit part. But an ambitious Helena isn't satisfied with her one-line character and sets her sights on a steamier role, leaving a dismayed Hunter to rethink her support. Elsewhere, Courtney and Johnny prepare to play a charity volleyball match with cast members of 'Popular'.

Courtney's hotshot boyfriend causes a stir on the set, and Johnny has to go out with the winner of a fan contest, who turns out to be a 14-year-old boy named Leslie.
