After an old witch is burned at the stake by the inquisition her two nun daughters execute a revenge which amounts to them seducing every man and woman that comes their way. Dealing with lust and anguish (frequent themes in Franco work),'Les démons' is quite a polished work by Franco's standards. Widescreen compositions are impressive and psychedelic music outstanding(a catchy guitar tune starts playing every time there is a bare flesh on the screen). Sadly Jess Franco didn't bother to hire a good cameraman, so some shots are out of focus, especially during zooms. Still, the camera-work in 'Les démons' is much better then in such later Jess Franco movies as 'White cannibal queen', for example. Regular Jess Franco actor Howard Vernon ("The awful Dr. Orloff") has a supporting role. Recommended for Franco admirers and those who find the idea of lesbian nuns hot.
