"Arkangel" is the second episode of the fourth series of the British science fiction anthology series Black Mirror. Written by series creator and showrunner Charlie Brooker and directed by Jodie Foster, it premiered on Netflix on 29 December 2017, along with the rest of series four. In the episode, the single mother Marie (Rosemarie DeWitt) enrols her daughter Sara in a trial of Arkangel, an implanted technology which allows Marie to track Sara's location, current vision and hearing, and automatically censors distressing material.

The main theme of the episode is helicopter parenting; as a woman raised by a single mother, Foster had many views which influenced the script, such as a more complex characterisation of Marie, and was given control of casting. For the filming in November 2016, Foster chose a location in Canada to represent working-class America. Differently-aged versions of Sara are played by different actors, with Brenna Harding playing her as a teenager.

Critics saw Marie as a parent afflicted with much anxiety and guilt and compared Arkangel to existing technologies for child monitoring, such as microchip implants and smartwatches. They were mostly laudatory of Foster's directing style and DeWitt's acting but less complimentary of the storyline and moral, which were seen as simplistic, with many reviewers suggesting themes the episode could have explored in more detail. In one scene, a nurse incorrectly implies that an emergency contraception (EC) pill induces abortion, rather than preventing pregnancy. The episode was poorly received in comparison to other Black Mirror episodes.

Plot

Single mother Marie Sambrell (Rosemarie DeWitt) gives birth to her daughter Sara and raises her with help from her father, Russ (Nicholas Campbell). Three-year-old Sara (Aniya Hodge) gets lost following a cat and a distressed Marie has to enlist help from neighbours to locate her. Afterwards, Marie signs her up for a trial of Arkangel, a child monitoring system installed via an implant. Marie can monitor Sara's vision and hearing with a tablet computer, along with viewing live medical data and past audiovisual feeds. A filter can censor stimuli when they cause Sara stress, such as an intimidating neighbourhood dog. Shortly after, Russ survives a stroke, because Marie is notified when Sara, observing Russ, experiences stress.

Six years later, Russ has died. A classmate—Trick (Nicky Torchia)—tries to show Sara (Sarah Abbott) sexual and violent imagery but the filter blurs it. Sara draws blood from her finger, trying to learn what it looks like, so Marie has her assessed by a psychologist who recommends that she dispose of Arkangel, which is soon to be banned. Marie deactivates the filter and stores the tablet in the attic. An anxious Sara goes to school unsupervised and Trick shows her pornography and gore videos.

Aged fifteen, Sara (Brenna Harding) lies to her mother about going to a friend's house to attend a party with Trick (Owen Teague). Marie discovers the lie and after failing to contact her, turns on Arkangel. She sees Sara having sex for the first time, with Trick. Marie starts to use the tablet again and soon sees Sara snorting cocaine that Trick—who deals drugs—gives her.

Identifying Trick with a reverse image search, Marie confronts him at work and blackmails him to stay away from Sara. After receiving an Arkangel notification that Sara is pregnant, Marie sneaks an emergency contraceptive pill into Sara's smoothie. She later vomits and is told by a nurse that the pill caused it. Sara confronts Marie and forces the tablet away from her. The stress filter is accidentally reactivated. Unable to see the damage she is causing, Sara beats Marie unconscious with the tablet, breaking it.

The filter deactivates and Sara runs away. When Marie regains consciousness, she frantically yells for Sara down the street. A hitch-hiking Sara gets into a truck.

Production

Whilst series one and two of Black Mirror were shown on Channel 4 in the UK, in September 2015 Netflix commissioned the series for 12 episodes, and in March 2016 it outbid Channel 4 for the rights to distribute the series in the UK, with a bid of $40 million. The 12-episode order was divided into two series of six episodes each, with "Arkangel" in the latter group. The six episodes in series four were released on Netflix simultaneously on 29 December 2017. "Arkangel" is listed as the second episode, but as Black Mirror is an anthology series, each instalment can be watched in any order.
