CW is first seen in a luxurious home, overwhelmed by unseen notifications pinging on her phone, and the tension culminates in her slitting her own throat.
In Southern France, CW—having escaped from Thailand and started a new life—and her girlfriend Diane celebrate their first couple’s birthday. CW grows frustrated with influencer Charlotte, who snagged their top hotel room at the last minute and keeps pressuring them to attend a string of events. The friction peaks when CW kills Charlotte and impersonates her on social media.
A few days later, a wary Diane digs through CW’s belongings and uncovers fake passports and links to previous murders, including Charlotte. CW tries to talk her way out, but Diane calls her a psychopath. Enraged, CW strangles Diane to death, then regrets the act and escapes to Bali, using Diane’s voice as a personal A.I. assistant to cope with her grief.
Meanwhile, Madison, the survivor from the first movie, has kept a low profile while enduring constant cyberbullying as the prime suspect in the murders of her boyfriend and several other women killed by CW, who remains unfound. Despite being cleared of charges, she travels to France after learning about the mysterious murder of an influencer (Charlotte) and spots CW and Diane in Charlotte’s Instagram photos, later discovering CW’s Bali trip from Diane’s mother.
In Bali, Madison and CW cross paths with Jacob, a masculinist influencer, and his girlfriend Ariana, a conservative influencer who turns out to be the woman from the intro. The pair use Jacob to hunt or foil the other, each claiming the other is the true murderer.
As events unfold, Jacob grows suspicious of CW, but CW hacks his computer and posts private videos that expose him and Ariana as a candaulist couple. Ariana, confronted with her own private life laid bare, takes her own life.
Madison and CW finally reunite and clash over Ariana’s death, a confrontation that escalates into a fight leaving Jacob injured and CW unconscious. Madison then locates CW’s hideout and belongings, while Jacob discovers CW has posted his private videos, prompting CW to stab him to death on a live stream that exposes her to the world.
The live broadcast draws hundreds of viewers who weigh in with comments about CW’s appearance, question the authenticity of the footage, or praise Jacob’s death. In a final, unhinged spree, CW chases and butcher’s Jacob’s best friend and his followers as the credits roll.
