After an inquest determines that egotistical Jeff Ambler has committed suicide, six of his acquaintances, some of whom were financial backers of his art gallery, gather together, unconvinced by the ruling.
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.
