Depraved and sadistic Nazi scientist Dr. Ellen Kratsch (excellently played with lip-smacking wicked relish by the lovely Macha Magall) creates a brutish sex-crazed Neatherthal subhuman beast (hysterically portrayed with slobbering grunting gusto by tubby wonder Salvatore Baccaro) who rapes and eats beautiful young women who get tossed in its cage. Meanwhile, a guerrilla army of dedicated freedom fighters try to liberate Northern Italy from the cruel tyranny of the Third Reich. Writer/director Luigi Batzella scrupulously covers all the supremely seamy and revolting exploitation bases: plentiful tasty female nudity (several guys show their stuff as well), an unsparingly mean and sordid tone, savage animalistic rape (the beasts rips out one hapless victim's pubic hair and devours it by the handful!), truly vile and hateful Nazi villains, vicious, kinky, and excruciatingly graphic torture set pieces that include a gal having her stomach chewed open by rats, another chick having her fingernails yanked out with pliers, a horny male prisoner getting castrated by a topless Krastch, and, in the gloriously tasteless highlight, a little baby is tossed up in the air and heartlessly blown away by the loathsome Nazi swine; and an uncompromisingly gloomy ending. The lousy dubbing, cruddy (far from) special effects (the chintzy Tonka Toy plastic bomber plane in particular in is uproariously shoddy), Ugo Brunelli's crude cinematography, liberal use of obvious poor quality stock footage, Giuliano Sorgin's redundant shuddery synthesizer score, and the clumsily staged action scenes further add to this lovably appalling atrocity's considerable grimy charm. Entertaining low-grade junk.
