Peppermint was released in the United States on September 7, 2018, to negative reviews from critics and the film grossed $53 million worldwide.

Five years earlier, the same woman, Riley North, is working as a banker in Los Angeles, struggling to make ends meet.

Peg, an obnoxious rich woman with a bratty daughter who looks down on Riley, schedules a party on Carly's birthday to ruin her day.

The LAPD detectives handling the case are hesitant to pursue charges against the three, as Garcia wields considerable power and influence.

Judge Stevens, who is secretly on the cartel's payroll, declares there is insufficient evidence to allow the perpetrators to stand trial and dismisses the case, while the prosecuting lawyers do nothing.

Five years later, Detectives Moises Beltran and Stan Carmichael arrive at the site of the carnival and find the three shooters hanging from the Ferris wheel, having been killed by Riley.

He also agrees with what she did by helping him expose dirty cops in his department and slips her the key to her handcuffs, allowing Riley to escape again and go where she is needed.

[4] In August 2017, Jennifer Garner was in talks to join the film as Riley North, a woman who, driven by the deaths of her daughter and husband, killed by a cartel, wages a one-woman war on crime using various weapons.

[5][6] The title of the film, "Peppermint", refers both to the flavor of ice-cream the character's daughter was eating upon her death, and the eventual alias taken by her as she embarks on her crusade.

[2] In the United States and Canada, Peppermint was released alongside The Nun and God Bless the Broken Road, and was projected to gross $10–13 million from 2,980 theaters in its opening weekend.

The website's critical consensus reads, "Far from refreshing, Peppermint wastes strong work from Jennifer Garner on a dreary vigilante-revenge story that lacks unique twists or visceral thrills.

[16] Frank Scheck of The Hollywood Reporter called the film "Death Wish on steroids", and said it "lacks subtlety and anything even remotely resembling credibility, but, like its heroine, it certainly gets the job done".

[20] Richard Roeper of the Chicago Sun-Times gave the film two out of four stars, writing, "In the stylishly directed but gratuitously nasty and cliché-riddled Peppermint, Garner plays essentially two characters cut from the same person.

"[21] Writing for TheWrap, Todd Gilchrist said that Peppermint "ultimately possesses the stale predictability of an unwrapped candy discovered at the bottom of a purse.

"[22] Andrew Barker of Variety wrote: "Garner gives everything that is asked of her, from brute physicality to dewy-eyed tenderness, but this half-witted calamity botches just about everything else.
