Two strangers who wreck their cars on a rural highway during a storm take refuge in a mansion. A doctor, who has left an unconscious woman, Susan, 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.
