Stephen Graham as Matthew Collins

As mentioned, Stephen Graham plays Matthew Collins, a Hope Not Hate activist and investigative journalist who spends his time trying to prevent people from joining far-right groups – the very ones he was once a part of. Matthew then seeks to find someone to infiltrate one group by sending in an imposter (or 'Walk-In') to seek information about a plot to murder an MP.

Stephen is known for being in plenty of memorable roles throughout his career. His previous credits include: This Is England, Peaky Blinders, Line of Duty, Boardwalk Empire and films such as The Irishman.

Leanne Best as Alison

Alison is Matthew's partner and mother to his two children. The family have had to move several times due to the volume of threats they had received as a result of Matthew's work to bring down hateful groups. In the drama, it's clear her husband's work also has an effect on her. Alison is played by Leanne Best who is known for starring in Close To Me, Four Lives and more.
