Donna Summer is playing on the stereo. Dishes of cheese and pineapple are on the coffee table. The social get-together from hell is about to begin. Beverly and estate agent husband Laurence have invited round new neighbours Tony and Ange and nervous divorcee Sue, twitchy about the party her fifteen-year-old daughter, Abigail, is throwing. As Beverly plies the guests with alcohol, cigarettes, Demis Roussos and nibbles, this horribly compelling evening descends into drunkenness and debauchery.
