A few unattractive but not particularly chunky gals play a desperate game of "I'm so fat I might as well demean myself."
During what is supposed to be some sort of sorority gathering, three girls have a hissy-fit over their fourth skinny friend. This is the movie's premise for why the girls have decided that their only hope is to throw themselves at men that find them disgusting. What is really disgusting is the dialog that follows as each girl shows how pathetic she is by begging for sex so that she might feel better about herself.
There is of course one woman that does not succumb to the degradation and that is headmistress Kiki D'Aire. Looking fairly trim and carrying extra weight only in her voluptuous breasts, Kiki gives a quick and half-hearted fuck to the resident Peeping Tom, Jeremy Steele.
