DCI John Luther is still on the job - ex-wife Zoe's boyfriend Mark North doesn't pursue the assault charge - and he now investigates the murder of two police officers who were lured to site by a 999 call and then shot. CCTV footage suggest that someone with a military bearing was in the area and it leads him to Owen Lynch, a former Royal Marine who was discharged due to psychological problems. His father Terry, also a formal Royal Marine, is in prison for having killed a police officer some 18 months before and Luther believes he's out for revenge. Meanwhile, Alice Morgan contacts Luther and lets him know that she has decided to investigate him. She also threatens Zoe.

During this episode, the character Owen Lynch (Sam Spruell) uses the phrase, 'Ever get the feeling you've been cheated?' This is exactly what Johnny Rotten says at the end of the Sex Pistols last gig in USA before they split. See more
When Owen was filming himself he referred to Forty-Six Commando (a fictitious unit). No Royal Marine would say Forty-Six Commando; he would say Four Six Commando. See more
