There are three excellent instalments of The Capture to enjoy, and each is more gripping than the last. The first two saw Holliday Grainger's DI Rachel Carey race against the clock to get to the bottom of two major conspiracies that involved video manipulation. Series three, which aired earlier this year, picks up a year after she broadcast a live deepfake of a government minister to the nation and her hopes to regain the public’s trust in surveillance technology are thrown off course when an act of terror occurs. Pure genius. Available to watch now on BBC iPlayer.
