'SS Girls' aka 'Casa Privata per le SS' (1977) - Bruno Mattei.

Revered schlock-Meister General, Bruno Mattei's enjoyably sleazy reiteration of 'Salon kitty gives sin-seeking viewers a voyeuristic peek into the smuttier machinations of WW2 subterfuge. Set at the end of the war, the German high command desperately attempt to root out the traitorously plotting Generals by erotic means voluptuous! Following a lustful, monumentally boozy bacchanal, the drunkenly revelling conspirators are unmasked and promptly put to death by the plainly psychotic, pseudo Crispin Glover-alike despot, Herr Shellenberg (Gabriele Carrara). Crude, frequently lewd, and morally bankrupt, Mattei's gaudily goose-stepping shunt-fest employs a colourful cornucopia of boorish bonkage and assuredly sordid S&M shenanigans to maintain interest. 

Undeniably Nazisploitation gold, cheaply made with impeccably bad taste, notorious plagiarist, Bruno Mattei dutifully delivers the reich stuff with his gorgeously grubby 'SS Girls'. The performances, text, production values, and cinematography are far better than one might expect, but the cinematic competence does very little to mute the triumphant trashiness of it all! While it, perhaps, lacks a truly gonzo climax, it's mostly fun, and the groovy sore by, Gianni Marchetti, is, for me, a genuine highlight of Mattei's mucky master race gang bang!
