This film dates from 1969 - shortly after the Hays Code collapsed under the weight of multiple threats from TV, foreign films and domestic disobedience.
However, despite that, this cheapo effort has every man still clad in underpants (and sometimes socks) as they grapple with multiple women - some also retaining their knickers.
Briefly pretending to flesh out the official "plot" of a supposedly-professional bankrobbing girl gang, most of the "action" is actually devoted to the lesbian and hetero shenanigans that were presumably the main attraction for the then-contemporary audience, who had yet to be lost to the imminent hardcore tidal wave (or the newly-acceptable softcore content of mainstream hollywood). Apart from a short inventive scene featuring a toaster, that's pretty much it.
Admirably short, and worth a look if this sounds like your kind of retro fun, but it's really not very good.
