Monster: The John Wayne Gacey Story is an American crime drama television miniseries created by Jane Holloway for HBO. Initially announced under the working title Dark Pursuit, the project was rebranded in September 2025 to align with the Monster anthology franchise. The eight-episode series is directed by Lena Ortega and dramatizes the life and crimes of serial killer John Wayne Gacy.

The series stars Michael Shannon as Gacy, with Paul Dano, Kaitlyn Dever, Nick Offerman, and Jovan Adepo in major roles. Supporting actors include Bill Camp, Jessie Buckley, Jeremy Allen White, Mary Elizabeth Winstead, and Scoot McNairy, with guest appearances from Patton Oswalt, Lili Taylor, and Lucas Hedges.

The show premiered on February 8, 2026, and airs weekly on HBO, with episodes available for streaming on Max. Billed as one of HBO’s darkest limited series to date, it blends dramatized events with an examination of the institutional failures that allowed Gacy’s crimes to remain hidden for years.

Episodes

No.	Title	Original air date
1	"The Clown"	February 8, 2026 (2026-02-08)
In 1972, contractor and part-time entertainer John Wayne Gacy appears at a suburban Illinois street fair, dressed as "Pogo the Clown" while mingling with neighbors and local officials. His cheerful public demeanor contrasts with ominous scenes inside his home, where a locked basement door hints at hidden horrors. Gacy expands his reputation by volunteering at Democratic Party events and offering work through his contracting company, drawing in vulnerable young men such as Tim Kelly. When Tim vanishes after attending one of Gacy’s gatherings, police dismiss the family’s report as another runaway case. The narrative underscores institutional blind spots and missed warnings. In the closing sequence, Gacy silently removes his makeup at a bathroom mirror, his reflection vacant as muffled cries seep from beneath the floorboards.
2	"House of Secrets"	February 15, 2026 (2026-02-15)
Detectives canvass neighborhoods following Tim’s disappearance, with Harmon questioning Gacy directly. Gacy deflects suspicion by echoing authorities’ claims that the boy likely ran away. Meanwhile, Harding compiles cases of missing young men from surrounding towns, noticing striking similarities in the accounts of parents. Her editor warns her against “fearmongering,” but she persists. Rivers, an apprentice employed by Gacy, grows uneasy after hearing rattling from a locked crawl space during late-night work. The episode climaxes with a backyard barbecue where Gacy entertains guests while ominous shots linger beneath the house, water dripping and muffled sounds barely audible. Rivers stares at the crawl space door, his unease signaling that the danger is no longer hidden from those closest to him.
3	"Missing Boys"	February 22, 2026 (2026-02-22)
A montage shows families posting missing posters across town as police dismiss most cases as runaways. Wells becomes the emotional centerpiece, grieving her son’s disappearance and refusing to accept official explanations. Harmon begins linking missing persons cases, but Crampton argues resources cannot be spared. Harmon notes that many victims once worked for Gacy’s contracting business. Harding publishes her first article tying Gacy to the disappearances, sparking uproar in the community, where some defend him while others whisper doubts. Rivers confronts Gacy about crawl space noises, only to be mocked and gaslit. The episode ends at a candlelight vigil where grieving families gather; Gacy himself attends, shaking hands with parents as Harmon stares at a wall of missing boy photos, realizing the true scale of the case.
4	"The Double Life"	March 1, 2026 (2026-03-01)
Gacy attends a local political fundraiser where Rayner praises him as a model citizen, but intercut sequences show his private life unraveling. For the first time, the narrative depicts Gacy luring young men into his home under the pretense of work or parties, employing the “handcuff trick” in a chilling scene that shifts from playful to violent. Rivers, increasingly fearful, hears cries echoing from beneath the floorboards while cleaning tools in the garage. When he confronts Gacy, he is dismissed with mocking laughter. The second half enters the crawl space itself, revealing narrow tunnels, dirt walls, and hidden bodies. The episode ends with Gacy entertaining children at a birthday party, painting a balloon with a grotesque smile as the camera cuts between laughing guests above and the grim reality below.
5	"Buried Beneath"	March 8, 2026 (2026-03-08)
Harmon grows increasingly obsessed as he studies a map of missing boys, confronting Crampton over inaction and pushing for surveillance on Gacy. Harding publishes a follow-up article that directly names Gacy as a link in the disappearances, inciting outrage at town hall meetings. In the shadows, Gacy deflects criticism by portraying himself as a persecuted neighbor. Rivers, overwhelmed by paranoia, sneaks back into the house and discovers disturbed soil in the crawl space, fleeing in horror before uncovering more. Later, Harmon tails Gacy to a remote field where he observes him digging at night in eerie silence. The episode ends with Gacy waving from a Christmas parade in clown costume, unaware that police are quietly preparing warrants as the community still sees him as a smiling friend.
6	"The Search Tightens"	March 15, 2026 (2026-03-15)
7	"Confessions"	March 22, 2026 (2026-03-22)
8	"The Crawl Space"	March 29, 2026 (2026-03-29)
