Jessica Alba just sold off her health and beauty company for a nice piece of change. It wasn’t that long ago that the “Dark Angel” alumna finished a run on her latest series, “L.A.’s Finest.” So it’s not like she needs the work.

But when Netflix comes calling with a check and ther offer of another thriller for the veteran action heroine to brawl, stab and head-butt her way through, it’s limber-up time.

“Trigger Warning” is a time-tested vengeance Western given modern combat, arms-smuggling and right wing politics trappings.

Alba plays a special forces commando of some sort, a woman we meet when her team is chased across some piece of Syria because the locals “figured out were aren’t aid workers.”

Parker is a tough broad you want on your side in a scuffle. She’s the type who has to be reminded “You can’t solve every problem with a knife.”

The moment we hear that, we figure that’s exactly what she’s about to do. A call from “back home” tells her that her father died in an accident in an old mine he owned next to the family cantina, Maria’s.

Returning to the desert Southwest, Parker’s old love, the sheriff (Mark Webber) has more doubts about the cause of death than she does. But the suggestion that Dad (Alejandro De Hoyos) might have killed himself, or died because he was clumsy at using grenades to open mine shafts, gets her back up.

Father Frank was a former Green Beret. He knows which end of a grenade to toss and which to keep as a souvenir.

Elvis (Jake Weary), the scumbag brother of our sheriff, drops hints and sets off alarm bells in his belligerent come-ons and Big Man in Town bluster. And since he’s not just the sheriff’s punk sibling, but they’re both the sons of a MAGA Senator (Anthony Michael Hall) running for re-election, Parker starts to piece together clues and connections and wonder what this right wing cabal with a stranglehold on the town and local “justice” is up to, and is capable of.

Alba’s still in fine fighting form and the sound effects team makes every stab, slice, hack and cut “thwick thwick shtick” through flesh with authority. Because Parker’s going to have to blade her way through a lot of minions to get to the truth.

But the story’s “twists” don’t merit the use of the word, and the action beats are generic in the extreme — big explosions here and there, shoot-outs, sniping and fist-fighting and pissed-off beat-downs.

There’s no reason the willowy Alba shouldn’t enjoy a long, two-fisted career thanks to her mastery of fight choreography. She’s more credible in a brawl than “Resident Evil” model/actress Milla Jovovich, if perhaps less convincing than the brawnier Gina Carano.

But Alba’s been around long enough to know good scripts from crappy ones. And she’s rich enough to be choosier — getting better writers, seeking out the best fight choreographers, insisting on bigger name co-stars.

Why have the clout and the luxury of a big bank account if you’re not going to use it to up your game?
