Kristy Comes Home (2005)

Karl and Ruger are filmmakers who have persuaded Kristy, one of the biggest stars in sex films, to star in Karl's next movie. However, while Kristy may be a major draw, she also marches to her own drummer, and midway through the shooting schedule she decides to take a vacation in Cancun. At first, Karl and Ruger think they can just re-cast Kristy's role and move on without her, but the audition process does little but show them just how valuable Kristy truly is.
