Two strangers who wreck their cars on a rural highway during a storm take refuge in a mansion. A doctor (James Harris), who has left an unconscious woman, Susan (the striking Rita Calderoni), in his car walks in to discover depravities behind every door when Susan suddenly appears, dressed in a flowing gown and acting as if they were old friends. The next morning, Susan wakes up in his car and enters the mansion to find a leering aristocrat, his snaggle-toothed servant, and the doctor dressed as a count and acting like a decadent dilettante. It's as if the two exist in parallel universes, confronted with ghost versions of one another in a portal to the past controlled by a devilish hedonist.
