Bo Gyllenstake has been named heir to his wealthy uncle. The condition for receiving the inheritance is that his nephew proves himself to be well-behaved, but Gyllenstake's reputation is somewhat tarnished. He therefore starts a school for moral education on the family estate, where wealthy families send their troublesome daughters. The school naturally becomes a training ground for debauchery, where young upper-class women can live out their suppressed desires. Greedy relatives hire a lawyer to expose the truth and disinherit the heir. The prudish lawyer soon finds himself caught up in the sex carousel and is unable to report any misconduct.
