A sexy brunette (who looks like Julia Roberts’ little sister) is a meat inspector who doesn’t just examine shiny, store-bought hamburgers. This gal craves pant steak. She’s obsessed with a sex-addicted televangelist (played by Star Trek’s Chekov) and has sexy results with him. (One of the funnier moments comes when she’s knocking phasers with a guy who looks like Sulu while watching Chekov on TV.)
In-between mattress moshing and packing meat, the gal watches her favorite kung-fu show, The Girl With The Thunderbolt Kick. As destiny would have it, her brother — who runs a meat processing plant — has been selling tainted beef. This is not divulged to the sister, to whom he’s been giving the tube steak on a weekly basis. (He probably just forgot to mention it.)
So he infects her and her brain starts to do a buttsteak in a grinder. When she goes to the doctor, he speaks to her in Indian and she can totally understand him and responds…in English. He gives her a bunch of pills and then hits on her. Ick.
When she goes to church to confess her wrongness (“I had sexual intercourse 30 times…last week”), the priest tells her she’s committed mortal sins, but because her brain is broken, it comes out in a strange dialect, telling her to kill the Ten Tigers From Kwangtung (not real animals, metaphoric ones, i.e., everyone she’s been deeply romantic with in the past seven days). She does this with kung-fu moves, a flying guillotine (which makes for e-z decapitations), and some sort of sharp kitchen tools.
At this point if you’re lost as to the actual plot of Mad Cowgirl (2006), just let it happen; I couldn’t figure it out, either — and I totally eat steaks and watch kung-fu movies all the time.
