Divided They Fall

Season 4, Episode 3:

As a result of recent terror attacks, the British public have become fearful and increasingly conservative. Attacks and riots against asylum seekers are common and when a conservative MP crosses the floor to join a far-right party, The British Way, MI5 realise democracy is being threatened. Adam goes undercover in the British Way, tasked to turn a politically correct racist back to his aggressive roots whilst Fiona, posing as a lobbyist, undermines the MP in Westminster and Zaf embarks on a dirty tricks campaign. The pincer operation works perfectly but perhaps too effectively. The racist returns to his roots, entraps Adam and Ruth before hunting them down for sport.
