Pamela is a middle aged housewife who meets and becomes infatuated with a younger man, named Calvin, whom she meets at a party. Calvin shows up at her house the next day and makes an impression of Pamela's teenage daughter Susan. With Pamela's husband Felix away (and having a sexual tryst with his secretary) Pamela joins Calvin for a day out and finds herself at a debauched party complete with sex, drugs and true debauchery.
