You really must inflict the entire movie upon yourself sometime. It's unbelievably bad.
dead_cat Correction - that spoiler is from the novel this movie was "based on".
In the movie, Rusty drops out of the plot completely after he becomes (yet another) cabana boy for the character being played by an 80 year-old Mae West (I can't remember her name); in the novel he leaves after nearly beating Mae to death multiple times, then goes on to become a famous actor who is totally into butt.
BHWW It's a truly terrible film experience, a product 100% of that time Hollywood was trying to tap into that Sixties counterculture vibe with allegedly hip films, like Candy or Skidoo.
And while it's nothing compared to the shenanigans in Sexttete, the nightclub bit where Mae West "sings" a cover of an Otis Redding number is still quite nightmarish.
