| Ava and Nathan Bartlett are a Los Angeles couple expecting their first child in the midst of financial struggles and a failing marriage. They hire a charming plumber, Matt Pierce, to install their new toilet and Nathan quickly befriends him. While at a bar with Matt one night, Nathan shares a flirty interaction with a bartender, Chloe Lake, who is later brutally murdered in her apartment. The media reports Chloe as the latest victim of the "Westside Ripper", a local serial killer targeting young women. When the police find the same shoe covers as Matt's at the crime scene, Ava, a true-crime enthusiast, deduces that Matt is the Westside Ripper. She also noticed scratches on Matt's arms and connects him to the unsolved murder of a young woman in his apartment building in Pomona two years earlier. Instead of contacting the police, Ava proposes to Nathan that they start their own podcast so they can interview Matt. Despite initially declining, Nathan confronts Matt on a secluded beach and accuses him of being the Westside Ripper while Ava watches them from afar. ||||||

At the Beverly Club, LAPD detectives Quincy Burrell and Jessie Peterson question Nathan about his connection to Chloe and Matt. Nathan claims he vaguely remembers Chloe while admitting that Matt is his friend. Unnerved, Nathan insists to Ava that they hand Matt over to the police. The following day, Nathan discusses his proposal with Matt, denying Ava's involvement in order to protect her. To support his accusation, Nathan cites Matt's bloodstained shoe covers, his scratches, and the murdered Pomona woman. After Matt agrees to participate in the podcast, Ava and Nathan choose an empty warehouse as their recording location. Instead of meeting Nathan at the warehouse, Matt surprises Ava on her doorstep. ||||||

| Matt tells Ava that he knows she is the one who figured out that he is the Westside Ripper. He brings her to the warehouse with him and supplies the Bartletts with burner phones, while insisting on a new location for the podcast where they will not be easily identified. Matt also reveals that he has named Nathan as his alibi when the LAPD visited him. Ava learns from Ruby that the new season of Sisters in Crime, a hugely popular true-crime podcast, will also focus on the Westside Ripper. Matt takes Ava and Nathan to the new location, a mansion where he once installed a toilet. Matt names the podcast Based on a True Story and the trio records the first episode, in which Matt confesses he has murdered over 20 women. Dissatisfied with Ava and Nathan's cut of the first episode, Matt persuades them to upload his own cut, which he feels is more original. Ava convinces a hesitant Nathan to confirm Matt's alibi to the LAPD detectives. As the podcast goes live, the Bartletts anxiously check the download numbers. ||||||

The Lipinski sisters, the hosts of Sisters in Crime, introduce a surprise live speaker named Dahlia Stone, the supposedly sole survivor of the Westside Ripper, who is raising money for charity. During the panel, she recounts how she survived the Westside Ripper and asserts that she would instantly recognize him if she saw him again. Indignant, Matt assures Ava and Nathan that he has never met Dahlia and sets out to discredit her. Ava and Nathan run into Ruby and her lover Carlos, who are also attending CrimeCon. That night, Matt confronts Dahlia at the rooftop bar, accusing her of fabricating her survival story and running a charity fraud. Shortly afterward, Dahlia falls from the rooftop to her death, impaling herself on a patio umbrella in front of Ava, Nathan, Ruby, and Carlos while they are having dinner. ||||||

At a CrimeCon stall selling Westside Ripper merchandise, Matt meets a television writer who helps him realize that audiences crave "fresh content". Ava, Nathan, Ruby, and Carlos take ecstasy during a wild night of partying. The next morning, the Lipinski sisters' memorial tribute for Dahlia is interrupted by Matt hosting a live episode of Based on a True Story in another room. Using a voice changer, Matt remotely identifies himself as the Westside Ripper and confesses to pushing Dahlia to her death. As a large crowd gathers for the event, the Bartletts go to confront Matt, whereupon Ava drops her burner phone.

Ruby calls Matt on Ava's burner phone and sees him answer the call on his own burner. She confronts Ava with the burner, suspecting that Matt is the Westside Ripper. Ava convinces Ruby that she and Nathan, desperate for money, created a fake podcast where Matt merely pretends to be the Ripper. Nathan wants to reclaim his dog McEnroe, whom the Bartletts gave to Simon because their backyard was too small. During dinner, Carlos leaves Ruby after Simon bribes him. When Ava goes to console Ruby, Ruby blackmails Ava into letting her join the podcast, threatening to take Matt's glass with his fingerprints to the police, but Ava rebuffs Ruby. The podcast faces online backlash from numerous celebrities for its glorification of violence.

Matt takes Nathan to their usual bar to play darts, during which Matt attempts to convince Nathan to let him kill again to keep the podcast alive. Matt also advises Nathan not to feel guilty about McEnroe's death, leading Nathan to punch Matt in the face and strangle him to the ground. When Nathan returns home, Ruby stops by and seduces him in an effort to persuade him to let her into the podcast. Nathan drives Ava to the Malibu beach house that they have always wanted, but she feels that they need to resolve their marital problems before buying a house. An argument ensues, with Ava declaring that Nathan gave up on life after his tennis injury. Just as Ava is about to leave, she and Nathan are horrified to find Ruby's dead body with a dart in her neck on the doorstep. ||||||

Simon, who arrives uninvited at the party, steps outside with Nathan and proposes a reconciliation. When Ruby's phone starts ringing in the trunk, Nathan tells Simon that all is forgiven and rushes him back inside. Ava and Nathan find a voicemail on Ruby's phone from Detective Burrell regarding the Westside Ripper, confirming Matt's claim. While Matt and Tory are having a secret affair, the Bartletts go to the Beverly Club at night and bury Ruby's body in a pit on the tennis court, which will be sealed with cement the next day.
