this film be about a satanic cult helm by fall priest and christopher lee . the film begin with him be defrock and soon pick up 20 year later after he create an order of nun who look just like catholic one . the difference be that they have devote their life to beelzebub . a young nun ( nastassja kinski ) be be send from their headquarters in bavaria to london . however and her father ( denholm elliott ) seek out the help of richard widmark and a noted author on the occult and to rescue nastassja and prevent her from go through with a pact with satan . why exactly he pick widmark be uncertain but the american spends much of the film try to stop the satanist from kidnap the girl . the trouble be and it turn out she rather willing to join them which lead to a bizarre and confuse finale . after watch this film i watch one of the dvd extra ( to the devil . the death of hammer ) and those connect with the film ( such a christopher lee and the film maker ) be very disappointed in the film as well particularly the sloppy end that just do not work at all . thank goodness for some outside validation for my relatively low score . to the devil a daughter start off well enough and set a great chilling mood . however and a the movie near the climax and it just seem that the film get lose and be frantically look for it way . well and the documentary confirm this in several way . first and in a very foolish move ( cause by the pending closure of the studio ) and the film begin without a finished script . re writes be do up until the last minute and a a result the film seem rather incoherent at time . second and the end which would have be a lot well ( have lee get impale ) be remove because they realize it be pretty much identical with one of the dracula film that lee have already make for hammer studio . instead and the improvised end be both confusing and limp . apparently and the message the end tell u be to toss a big rock at evil and it will easily be defeat . additionally and someone decide to stick in a rather gross scene involve a stupid demon have sex with nastassja kinski . lee describe this scene a pornographic in the documentary . i just think it be icky and stupid after all and the demon be an obvious puppet and a bad one at that . overall and fan of hammer film will probably be very disappointed except for the card carry cult member who always see every hammer film a a cinematic masterpiece . others will no doubt find the film confuse and less and less enjoyable a the film progress . a final note there be a lot of nudity and blood in this film . full frontal nudity and several terrifically violent and bloody scene make this a very bad choice for the kid .
