Luther - Season 1

DCI John Luther returns to work after the traumatic arrest of a serial killer, and his first case is to investigate the seemingly perfect murder of a former child genius's parents. However, everything is not as it first seems, and when Luther is unable to find evidence to convict, he becomes embroiled in a battle of wits with the suspect - who has set her sights on him and his estranged wife.

DCI Luther must outmanoeuvre a trained sniper on a mission to kill police officers. But as the body count rises and the killer's true motives are revealed, Luther puts himself in the line of fire to try and draw the killer into the open. Meanwhile, Alice Morgan has been investigating Luther's past - and is threatening to tell Zoe what she has discovered.

DCI Luther finds himself on the trail of Satanic occult killer, Lucien Burgess, who was previously accused of kidnap and murder but escaped charges due to police misconduct. However, with a young mother's life at stake, Luther must now use all his skills to build an airtight case and seeks out guidance from Alice. Meanwhile, Mark is beaten up by a gang of young girls, and Zoe discovers her feelings for Luther remain strong even after she doubts his integrity.

When a serial killer goes on the rampage, Luther must put his personal life aside and delve inside the murderer's mind to discover what is driving him to kill so many girls, and why. Meanwhile, serial killer Henry Madsen wakes up from his coma, and Alice takes matters into her own hands when Luther cuts off contact with her.

When an art dealer's wife is taken hostage, Luther leads a tense investigation as the hostage takers request payment in diamonds. However, what Luther doesn't know is that the case will soon become very personal.

Framed for murder, Luther turns to Alice for help as he sets outs to prove his innocence, and exact revenge on the real killer. But while the two plot, DCI Reed is quietly shoring up evidence against Luther, as the rest of the team are forced to hunt him down.
