Ross Henderson was an influential vlogger rallying against the growing tide of the far right. As his audience tuned in to Henderson's latest live broadcast, they had front-row seats to his savage murder.

Alongside this volatile case, Detective Inspector Jake Porter finally has a lead on the hit-and-run which killed his wife. With his life in disarray, he and his partner DS Nick Styles struggle to prevent full-blown riots in the wake of the Henderson atrocity. And following the trail to his wife's killer will take its toll: Porter will have to act like a criminal in order to take down the person responsible, but there's no guarantee he will come out the other side alive.
