“Blink Twice” is the “Get Out” of “Believe women.”

Actress turned director and co-writer Zoë Kravitz aims high with this savage satire of women imperiled not just by murderously brutish men, but by their own false sense of safety in a world of glamour and extreme wealth, a world they take shortcuts to try and join.

And if her directing debut takes a while to settle on stakes and ratchet up suspense, if her idea of “foreshadowing” is delivered up with a sledgehammer, Kravitz’s messaging is blunt and the recriminations and consequences are bloody and righteously served.

Frida and Jess are two 30ish besties who do a bit of waitressing at catered events. And they’re all about getting in the door at the latest charitable shindig tossed by tech bro Slater King (Channing Tatum) for his charitable foundation.

Something’s scandalized King. He is infamous for his parties , but embarrassed enough to be constantly saying “I’m sorry” and that he’s “working on” himself to see that he stops doing whatever he was caught doing.

Visions of the crimes of Armie Hammer or Cosby or Trump can’t help but cross the mind.

That makes no difference to Frida (Naomi Ackie, who played Whitney Houston in “I Wanna DAnce with Somebody”), who seems positively infatuated. Her catering scolding her about being “too chatty” with the host at a previous event suggests she has history with this billionaire, and her scheme to get closer to him lets us know that she thinks she has a shot.

Cynical Jess (Alia Shawkat) is all about smuggling dresses and stilettos in so that they can slip out of “uniform” and into the crowd, where they will attempt to walk on heels like they’ve been doing it forever as they mingle with this King and his court. Christian Slater and Haley Joel Osment (“The Sixth Sense”) play old pals. Kyle MacLachlan plays Slater’s too-chummy psychotherapist.

It’s the infamous “private island” after party that the party girls crave. And sure enough, shy, sheepish Slater is charmed enough to bring them aboard. A baccanale of upscale dining (Simon Rex plays the chef pal), exotic booze and designer drugs on a Caribbean isle begins, with the five women (Adria Arjona, Liza Caribel and Trew Mullen) howling and dancing and swimming in matching white swimsuits, evening wear etc. provided by the helpful executive assistant Stacy (Geena Davis).

The guys — joined by young crypto-bro Lucas (nepo baby Levon Hawke) — are up for anything and everything, including deep sea fishing and spirited razzing.

But the way an old Latina servant keeps calling Frida “Red Robin,” the fixation Slater King has with “memory” and “forgetting,” the unpleasant edge that chef Cody, oldest pals Vic and Tom (Slater and Osment) exhibit around much younger and more attractive women raise eyebrows.

Jess is more blunt. “There’s something wrong with this place.” And sure enough, one and all — the app queen (Caribel), the bimbette (Mullen) and the “Hot Survivor Babes” TV starlet (Arjona) — will either find out or face the consequences.

Kravitz pounds home the props and “hints” of foreshadowing — Jess constantly searching for “my lighter,” the chef showing off “my special knife,” the one that Slater brought him from Okinawa, Frida’s fingernails with animal designs that are her side hustle.

Introducing a trained “Survivor” series athlete (Arjona) to the mix is entirely too on-the-nose.

But Ackie summons up calculation and naivete as our heroine — eyes on the prize, expecting a seduction at any moment, determined to see this through, no matter what misgivings her friend has. Arjona brilliantly flashes the pasted-on smile that threatened women instinctively reach for to fend off danger.

And Tatum is terrific as troubled, seemingly shy and charming “new money” with a deadly, narcissistic edge. His Slater is a good looking version of Elon Musk, just better at faking sincerity, a more butch Peter Thiel or Mark Zuckerberg, somebody testing the limits of unlimited wealth and celebrity in “power” terms.

Kravitz leans on extreme close-ups, isolated body part framing (faces, butt shots, cleavage surveys) to emphasize how the women here are viewed by male the Friends of Slater King.

Her script may underscore the obvious and even have characters say it aloud for everybody who has missed the point. But there are just enough cryptic twists to keep this engrossing and on message, all the way through the epilogue.

Late August, with schools back in session, has traditionally been a dumping ground for inferior films — the current “Crow” remake, etc. But Kravitz delivers an exception to that rule, a thriller with bite and a point of view that makes for a bracing, bloody chaser to a year of rising feminine rage barely masked in this week’s political expressions of feminine hope and joy.
