Overview
Devil in Disguise: John Wayne Gacy takes a well-known true-crime story and tells it through the investigation, the accounts of the victims and the people who must live with the aftermath. The eight-part Peacock miniseries traces the police case that started once Robert Piest went missing and slowly revealed how extensive Gacy's crimes were. Gacy is portrayed by Michael Chernus, while Gabriel Luna and James Badge Dale play the investigators Rafael Tovar and Joe Kozenczak. Sam Amirante, the defense attorney, is played by Michael Angarano, and Bill Kunkle, the prosecutor, is portrayed by Chris Sullivan.
The series places particular emphasis on how overlooked chances, bias and systemic failures let Gacy go undetected for years. By centering on the victims, it gives individual people and families more attention than a typical crime drama that focuses on the killer.
Quick Verdict
Devil in Disguise: John Wayne Gacy will appeal to those who enjoy serious true-crime dramas, investigative stories, and crime series driven by character. What sets it apart is its choice to devote substantial attention to victims, survivors, families, and investigators, rather than centering the narrative solely on Gacy.
Where to Watch Devil in Disguise: John Wayne Gacy in the US
Devil in Disguise: John Wayne Gacy is an eight-part American true-crime drama miniseries that reexamines the investigation into serial killer John Wayne Gacy while, crucially, keeping the victims and their families at the heart of the narrative. The series opens with the disappearance of teenager Robert Piest in the Chicago area, which steers investigators toward Gacy, a local businessman who appeared to be well respected. As Lieutenant Joe Kozenczak and Detective Rafael Tovar work the case, the investigation turns up evidence linking Gacy to many missing young men and boys. The narrative also traces defense attorney Sam Amirante, prosecutor Bill Kunkle, survivors, and families as they grapple with the aftermath of the crimes.
Created and written by Patrick Macmanus, the series dramatizes events based in part on the actual investigation and is connected to the 2021 Peacock documentary John Wayne Gacy: Devil in Disguise. Instead of focusing solely on Gacy, the 2025 drama explores the victims’ lives, the investigation, failures of institutions, and the sorrow endured by their families.
The limited series debuted on Peacock on October 16, 2025, with all eight episodes made available on the same day.
