Enter the dark and twisted world of the far right in this powerful drama based on a shocking true story as it follows a reformed racist, played by Stephen Graham, and his battle to foil a plot to kill an MP.

The five-parter, written by Jeff Pope, opens in 2015 with Matthew Collins determined to make amends for his past by working as a journalist for the anti-racist organisation Hope Not to Hate. Matthew is deeply concerned by a new extreme right-wing group called National Action, but his efforts to infiltrate them have failed.
