Entertaining from start to finish and wonderfully played by a largely female cast, David Arquette has a small role as an escaped convict, Grant’s film beautifully upends the sexist notion that women are naturally inclined to nurture. It surprises, too, as a tribute to the fortitude of working-class women.

This strange and anxious mixture of the Working Women comedies of yesteryear (think: 9 to 5, Baby Boom, and Working Girl) with the cramped hospital horror shows of our Saturday night sleepovers (recall: Visiting Hours, Halloween II, and Dream Warriors) is always compelling, always nerve-wracking, mostly funny, and agreeably gross.

12 Hour Shift doesn’t allow for quite the same kind of bravura showcase that Bettis gave us in “May” — Grant’s film, while plenty deranged in its own right, is nevertheless grounded in reality — but it still depends on the actor’s genius for being loathsome and lovable at the same time.

The material is edgy and at times outrageously gory and chaotic, but Bettis gives Mandy an exhausted, fed-up quality that keeps the movie on track, even (or maybe especially) when she’s pissed off about having to do everything herself.

12 Hour Shift never takes itself seriously enough to make the calamity that ensues anything more than “dumb fun,” and I mean that positively.

Grant’s screenplay builds a Rube Goldbergian narrative of escalating, piled-up crises, from which she also engineers a just-credible-enough exit strategy.

Bettis is perfectly cast as Mandy, her hazy disaffection to the increasingly bloody mayhem she has to deal with is best described as nonplussed irritation. Other performances are hit and miss.

The plot, geared as much for comedy as horror, is wound with efficient build-up, and its revolving-door atmosphere is consistent enough to paper over some iffy acting, baggy dialogue, and more than a few minutes of wasted real estate.

Actress turned director Brea Grant (TV’s “Eastsiders”) serves up a pungent, gory goof of a nurses-gone-bad comedy, dark as dirt and corrosive as Clorox.

The stage is set for all sorts of misadventures, and sure enough, Grant’s film leans into them, heavily, resulting in a film populated by repulsively stupid characters who keep making dumb decisions. The film’s premise has tons of potential, but you won’t find any of that here.
