Following the death of her wealthy husband, American socialite Kathryn West seeks seclusion at an Italian villa rented by her lawyer, Brian Sanders. She soon becomes bored, however, and welcomes the sudden appearance of Peter Donovan, a young American student whose car has broken down near the villa. After Peter seduces the willing Kathryn in the shower, he brings his "sister" Eva into the household and initiates a series of nightly orgies in which Kathryn's sexual desires are stimulated by alcohol and drugs. As the debauchery progresses, Peter dismisses the servants and makes Kathryn his prisoner. The Italian print has a different ending than the international release version.
