Fuck Fellini! Balls to Bicycle Thieves! High art be damned - this is what we want. Tattooed biker chicks armed with switchblades, sadistic schoolgirls smashing skulls, shower scenes, catfights, juvenile delinquent bitches on heat and much more. Japan has provided us with some of the most fucked-up movies on the face of the planet, and in this wonderful boxset we have four more outrageous 1970s exploitation flicks.

In Girl Boss Guerilla, a female biker gang fights for turf against a rival Yakuza mob who don't appreciate their cavalier approach. Imagine Switchblade Sisters with more tits, ass and torture and you're some way there.
