Two sisters run a hotel in some village in Spain, preparing meals for their guests, being hospitable and friendly, and killing young women whom they perceive as slutty, a perception that seems to include 99% of their young female guests, save for Laura, a conservatively clothed lady who is looking for her sister.
That'll be the sister who was accidentally killed for sunbathing topless on the roof of the hotel a mere five minutes prior to Laura arriving. The sisters tell Laura that her sister left early that day, which is an excuse she'll be hearing often regarding other guests. Slowly, Laura starts to figure out what's going on, but it could be that she's already too late to save herself...
This one has a kind of run of the mill plot but is saved by having two interesting murderers. One sister is a timid type who has a clandestine relationship with the young man who helps out at the hotel, while the other is the more aggressive type, constantly judging others while barely repressing her own sexual feelings, while her frustration manifests itself in murderous ways. There's a bit more depth to the two of them than just maniacal killers.
The major problem is not with the film itself, it's with the various presentations of it you'll potentially stumble over. Under the name of It Happened At Nightmare Inn the film runs for about 70 minutes, and it's recommended that you watch it under the name of Candle For The Devil, but there version I watched of that is also heavily cut. The Spanish version seems to be the most complete, because without that you'll have practically no idea of what's going on as such a hack job has been done on the film. While not over the top in terms of gore, you're still missing out on all the nudity and gore, so what's the point? The most shocking murder of the film is cut out almost completely, which harms the impact of the film greatly.
I've read somewhere that this is some kind of political allegory on the Franco regime, but I wouldn't have figured that out myself.
