Sweetie

The sexual problems of emotionally withdrawn Kay and her spiritual boyfriend, Louis, become exacerbated by the unexpected arrival of Kay's overweight, psychotic sister Dawn, aka Sweetie. Fresh out of the asylum, Sweetie has brought along her "manager," Bob, a continually zonked-out swinger who nurtures her unrealistic fantasies of becoming a star. As the two completely opposite sisters fight and rampage through the horribly furnished house, their father arrives with his own troubles: their mom has left him to find herself in the outback, as cook for an eccentric band of jack-a-roos.
