## Premise

Nida Huq ([Anjana Vasan](https://www.edgepedia.org/anjana-vasan)) is a meek shoe saleswoman at a department store in a northern English town in 1979. Her isolation is sharpened by the racism and anti-immigrant sentiment around her: her house is daubed with National Front graffiti, and a colleague, Vicky, is openly hostile and plans to vote for the National Front, an anti-immigration movement.<sup>[2](https://www.netflix.com/tudum/articles/black-mirror-demon-79-ending-explained)</sup><sup> • </sup><sup>[3](https://www.independent.co.uk/arts-entertainment/tv/reviews/black-mirror-season-6-review-episodes-ranked-b2357292.html)</sup><sup> • </sup><sup>[4](https://www.gamesradar.com/best-black-mirror-episodes/)</sup> While eating her lunch in the store basement, she discovers a talisman bearing a mysterious symbol; after cutting her finger, her blood activates it.<sup>[2](https://www.netflix.com/tudum/articles/black-mirror-demon-79-ending-explained)</sup><sup> • </sup><sup>[5](https://www.pluggedin.com/tv-reviews/black-mirror/)</sup>

The talisman summons a demon named Gaap ([Paapa Essiedu](https://www.edgepedia.org/paapa-essiedu)), who appears to Nida in the form of disco star Bobby Farrell of Boney M, a performer she has seen on television. Gaap explains that unless she carries out three human sacrifices over the next three days, the world will end on [May Day](https://www.edgepedia.org/may-day) 1979 in a fiery nuclear apocalypse.<sup>[2](https://www.netflix.com/tudum/articles/black-mirror-demon-79-ending-explained)</sup><sup> • </sup><sup>[3](https://www.independent.co.uk/arts-entertainment/tv/reviews/black-mirror-season-6-review-episodes-ranked-b2357292.html)</sup> Gaap reasons that three killings are minor against "an agonizing death for all". He also faces a penalty of his own: if the sacrifices are not made, he will be cast into eternal oblivion.<sup>[2](https://www.netflix.com/tudum/articles/black-mirror-demon-79-ending-explained)</sup><sup> • </sup><sup>[5](https://www.pluggedin.com/tv-reviews/black-mirror/)</sup>

Nida is not a natural murderer, so Gaap helps her select targets who "deserve" death by showing her visions of terrible deeds they have committed or will commit. Her first impulses include Vicky and a local man believed to have strangled his wife.<sup>[2](https://www.netflix.com/tudum/articles/black-mirror-demon-79-ending-explained)</sup><sup> • </sup><sup>[4](https://www.gamesradar.com/best-black-mirror-episodes/)</sup><sup> • </sup><sup>[5](https://www.pluggedin.com/tv-reviews/black-mirror/)</sup> For the final sacrifice she insists on the politician Michael Smart (David Shields), despite Gaap's urging to choose someone else; demons are fans of Smart, and the visions show Nida his future, a rising tide of fascism.<sup>[6](https://www.elle.com/culture/movies-tv/a44301942/black-mirror-season-6-episodes-ranked/)</sup>

## Ending

The deadline arrives and Nida does not prevent the apocalypse: fiery mushroom clouds destroy northern England on May Day, 1979.<sup>[2](https://www.netflix.com/tudum/articles/black-mirror-demon-79-ending-explained)</sup> Faced with death on Earth or an eternal oblivion outside it, Nida chooses to accompany Gaap into oblivion rather than stay behind. Reviews described the choice as a strange kind of optimism grounded in personal decision rather than in saving the world.<sup>[6](https://www.elle.com/culture/movies-tv/a44301942/black-mirror-season-6-episodes-ranked/)</sup><sup> • </sup><sup>[7](https://8flix.com/assets/transcripts/b/tt2085059/BLACK-MIRROR-S6-PRESS-PACK.pdf)</sup>

## Red Mirror and production

The title sequence reads "A RED MIRROR FILM", marking the episode, in Brooker's words, as "different-yet-adjacent to *Black Mirror*". He initially conceived it as the first episode of a companion retro-themed horror anthology series called Red Mirror, and said further episodes could be made under the label depending on the episode's success.<sup>[2](https://www.netflix.com/tudum/articles/black-mirror-demon-79-ending-explained)</sup>It was the first episode of series six to be written, though the last to air, and the only episode of the season not solely written by Brooker; Bisha K. Ali shares the screenplay credit.<sup>[8](https://www.televisual.com/news/black-mirror-hello-darkness-my-old-friend/)</sup> Essiedu, a fan of the series, described the story as "unique, political, funny and uniquely human".<sup>[9](https://www.netflix.com/tudum/videos/black-mirror-demon-79-behind-the-scenes-paapa-essiedu-anjana-vasan)</sup>

The past setting fits the season's wider shift: "Demon 79" was conceived for the retro-horror strand, "Beyond the Sea" was changed from a near-future story to one set in 1969, and "Mazey Day" is set in the mid-2000s. Brooker said that setting episodes in the past freed him from inventing technology-centered premises.<sup>[10](https://time.com/6287513/black-mirror-season-6-review/)</sup>

## Setting and themes

The episode's 1979 Britain is drawn from real conditions: the [Winter of Discontent](https://www.edgepedia.org/winter-of-discontent) of 1978 to 1979, months of industrial disputes, spiraling fuel costs, a crisis in [James Callaghan](https://www.edgepedia.org/james-callaghan)'s government, and right-wing agitation in the north of England. Critics noted that these issues felt strikingly present to viewers rather than purely nostalgic, reading the episode less as a prediction of a technological future than as commentary on the political present.<sup>[3](https://www.independent.co.uk/arts-entertainment/tv/reviews/black-mirror-season-6-review-episodes-ranked-b2357292.html)</sup><sup> • </sup><sup>[11](https://exhibitions.wienerholocaustlibrary.org/beware-this-poison/)</sup>

The supernatural framing also carries a reading about radicalization: one analysis argues that stripped of the demon, the story shows how an isolated, humiliated, scapegoated person can be handed a charismatic voice and an apocalyptic justification that reframes killing as saving the world.<sup>[12](https://www.howclosetoblackmirror.com/demon-79)</sup>

## Reception

On Rotten Tomatoes the episode holds 100% approval, from 14 reviews.<sup>[1](https://www.rottentomatoes.com/tv/black_mirror/s06/e05)</sup> Reviewers rated it four stars in *The Independent* and Vulture and 4.5 stars in Den of Geek, while *The Daily Telegraph* gave it five stars and called it "funny, gory" with what could be read as a happy ending.<sup>[3](https://www.independent.co.uk/arts-entertainment/tv/reviews/black-mirror-season-6-review-episodes-ranked-b2357292.html)</sup> Critics singled out the chemistry between Vasan and Essiedu, and Gaap's characterization drew particular praise; *The Guardian*'s Stuart Heritage attributed the episode's success to Essiedu.<sup>[6](https://www.elle.com/culture/movies-tv/a44301942/black-mirror-season-6-episodes-ranked/)</sup> Time ranked it second of the five episodes of season six, calling it the most conspicuous outlier in a season full of them and noting that it has no connection to technology, the future, or mass media.<sup>[13](https://time.com/6287186/black-mirror-season-6-episodes-ranked/)</sup>
