Biography
Duncan Pow worked as a programmer at the Granular corporation, whose latest breakthrough at the time was the creation of ADIs (Autonomous Drone Insects) in the form of the critically-endangered honeybees to pollenate flowers on their behalf. One day, Garrett's co-worker and flatmate, Tess Wallander, had attempted suicide after receiving online death threats over posting a picture of a mentally disabled man who threatened her at work. Though Garrett saved Tess's life, he leaves Granular.

After some time, several of the ADI's are involved in the gruesome deaths of immediate controversial figures, including conservative blogger Jo Powers and rapper Tusk, after pictures of them are posted alongside the hashtag DeathTo on Twitter. Detective Karin Parke and her partner Blue Coulson quickly make the connection, also learning the ADI's had facial recognition software implanted into them to be used by the British government to spy on its citizens (the only reason the ADI's were funded at all), allowing them to also find their targets more easily. Despite having found this information, they are unable to prevent the death of a British tourist who caught flack for pretending to urinate on a war memorial.

Once news of #DeathTo and its abilities breaks out, hundreds of thousands of people begin using it the next day, using the hashtag to vote for Chancellor of the Exchequer Tom Pickering to become the next person killed. Gaining access into the hard drive inside one of the ADIs, Coulson discovers a digital manifesto written by Scholes criticizing people acting against others behind a wall of anonymity.

Tracing the location where he took a selfie posted inside the manifesto leads authorities to a building where a partially burned disc drive is found, containing a backdoor program that will allow Granular to shut the ADI program down. However, Parke and Coulson also discover a cache of International Mobile Equipment Identity numbers of every phone of every person who used #DeathTo. They then realize that the people targeted by #DeathTo are not Scholes's targets, but the people using them. Despite their pleas to wait for a better decision, NCA officer Shaun Li executes the program to shut the ADIs down, but instead triggers every ADI in England to attack everyone who used #DeathTo. In the end, over 380,000 people are killed.

After realizing that he has been found out, Scholes shaves his beard and head and dumps his clothes and computer into a ravine, destroying and hiding any clues to his whereabouts. However, Coulson, who partially blames herself for the casualties caused, fakes her death and tracks Scholes' down to where he is hiding, the episode ending with her following him down a winding road with the implied intention of killing him.
