Honeymooning in Bavaria, a young couple becomes stranded and is forced to stay the night in the area. Doctor Ravna, owner of the impressive chateau that sits imposingly above the village, invites them to dinner that evening. Their association with Ravna and his charming, beautiful family is to prove disastrous.
