Looking for a little rest and time by herself, Betty rents a summer share at the beach. But Betty's luck turns to delicious lunacy when this sensible Everywoman gets drawn into the chaotic world of some very unsavory housemates - her friend Trudy, who talks too much; the lewd, seminaked Buck, who tries to have sex with everyone; and Keith, a serial killer who hides in his room with a mysterious hatbox. With sand between her toes, walking a thin line between sanity and survival, poor Betty will leave her summer vacation more terrorized than tan.
