Luther, Seasons 1-5

DCI John Luther returns to work after a spell of leave following the traumatic arrest of the serial killer Henry Madsen. Luther's first case is investigating the murder of the parents of child genius, Alice Morgan. He quickly deduces that Alice is responsible for the deaths, but the seemingly perfect crime leaves no evidence with which to convict her.

Luther must out maneuver a trained sniper on a mission to kill police officers. But as the body count rises, he has to uncover the killer's true motives. Meanwhile, Alice has been investigating Luther and to his horror, seems to know what happened to Madsen during his arrest. She baits him further by asking what Zoe would think if she knew the truth.

Kirsten Ross, a young mother, has been abducted. Luther realises that this is the work of Lucien Burgess, a collector and writer of the occult, who was suspected of the murder of another woman, Grace Allen, 10 years previously; but Burgess was never charged.

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, the man responsible for Luther's extended leave, has woken up from his coma. Because of Madsen, it's too dangerous for Luther to see Alice any more, but can she ever accept this?

When an art dealer's wife is taken hostage at gunpoint, Luther leads a tense investigation. The hostage takers want payment in diamonds so, stalling for time, Luther substitutes a bag of replacement diamonds from the Serious Crime Unit's evidence safe. Luther and DCI Reed are on hand to arrest the gang members picking up the gems, but when everything starts to unravel Luther begins to suspect that even Reed has double-crossed him.

Framed for murder, the only person DCI John Luther can turn to for help is Alice. DCI Reed remains at the heart of the police team, quietly shoring up the evidence against Luther from within. Even Rose Teller, Luther's former stalwart supporter, now leans on Reed for emotional support. To have any chance of escaping Reed's web of lies Luther must steal the evidence and discredit him. But can Alice really be trusted?

Still plagued by the death of his ex-wife, Luther returns to work to face a surreal and nightmarish case of a masked murderer determined to enter into folklore. As the body count rises, Luther must use all his skills to stop the killer, at the same time trying to rescue an old acquaintance's daughter from the dangerous world of prostitution.

Luther must rescue Ripley, abducted by Cameron, in time to prevent Cameron's final murderous set piece. But Jenny's ruthless and vengeful boss is demanding compensation for stealing her protégé. Luther is torn. Will his visionary mind provide the team with the tools to save Ripley and the killer's intended victims, or will his focus be compromised?

As Luther's affection for Jenny grows so does his determination to protect her and help her back on her feet. Baba, however, is determined to keep Luther on a tight leash. To add to Luther's difficulties, he is called in to investigate a man whose brutal and escalating murders seem to have no motive, leaving Jenny alone and vulnerable.

Luther's personal and professional life spirals out of control as he tries to cover up Toby's death and appease a suspicious Baba. He must also protect Jenny from any further harm. At work there's also a killer at large whose actions are ruled by his dice. How do you stop a man who sees life and death as a game and whose actions can't be predicted?

A chance encounter means Luther might be on the verge of finding love. But nothing comes easily - not when a fetish killer is on the hunt, not when an internet tormentor has had the tables turned and not when his worst enemies are his own colleagues.

Luther discovers the fetish killer is re-enacting the past. Can he stop him before he kills again? Meanwhile Ripley has to choose whether to turn a blind eye to Luther's unorthodox policing or betray him on record.

Luther must confront his demons when a vigilante killer embarks on a crusade to punish past offenders. Meanwhile the campaign within the force to bring him down knows no bounds, threatening everything Luther holds dear and pushing him to his limits.

Accused of crimes he hasn't committed, Luther must work quickly to clear his name and stop the vigilante killer from becoming a martyr. But in becoming the killer's target, it's not just his own life he risks, but the lives of those he loves.

On a leave of absence from the police force, Luther is laying low in a rundown cottage on the edge of England. But a visit from his old colleagues at the Met brings a shocking piece of news that draws him back to London in search of the truth. Meanwhile, a gruesome serial killer has struck the city, eating body parts as he goes. With a trail of clues leading from one crime scene to the next, Schenk and his team must work out the twisted logic that connects each victim.

On the trail of a horrifying cannibalistic killer, Luther is dogged at every step by ghosts from his past. Isolated and on edge, it takes every fibre of Luther's being to keep it together. Can a cold case help unlock a mystery that's tormenting him to distraction? Meanwhile, the serial killer is still on the loose. Benny's hacking skills have revealed a list of hundreds of potential victims but, with a rapidly escalating number of crime scenes, Luther must use all his ingenuity to work out where the killer is headed next.

While the monstrous and seemingly indiscriminate killings become ever more audacious and public, Luther and new recruit D.S. Catherine Halliday are confounded by a complex tangle of leads and misdirection that seems designed to protect an untouchable corruption.

The police and Cornelius converge on Luther's home. With Halliday convinced that the body in the morgue isn't their killer, can Luther put his own troubles to one side and find the true murderer before they strike again?

With his friend in peril and a young woman kidnapped by the relentless serial killer, can Luther protect the innocent while preventing Cornelius' violent revenge from consuming him? Who is Luther willing to save, and who can't he bear to lose?

With Luther's increasing absence from the case, Halliday leads the hunt for a monster on the loose - a killer determined to complete his final macabre masterpiece…
