In 1950's Britain, a group of decadent aristocrats operate their own 'secret season', an alternative to the tedious official round of balls and court presentations. Instead of being groomed for marriage, pretty young 'debutantes' are trained, tormented and finally auctioned off in a bizarre parody of the real debutantes' presentation at court. Angel Carstairs is inducted into this secret world and soon consumed by curiosity - which of these cruel men and women will acquire her?
