Idris Elba returns to his role as DCI John Luther for the fifth season of Luther, created by Emmy-nominated writer Neil Cross and produced by BBC Studios.
Dermot Crowley, Michael Smiley and Patrick Malahide return for the four-part season as DSU Martin Schenk, Benny Silver and George Cornelius; and Wunmi Mosaku, who won a BAFTA for her performance in BBC One's Damilola, Our Loved Boy in 2017, will join as new recruit D.S. Catherine Halliday.
When the moonless shadows of London give birth to a new nightmare, DCI John Luther (Idris Elba) must once again confront the depths of human depravity.
As a series of monstrous killings becomes ever more audacious, Luther and new recruit D.S. Catherine Halliday (Wunmi Mosaku) are confounded by a tangle of leads and misdirection that seems designed to protect an unspeakable horror.
But even as the case brings him closer than ever to the nature of true evil, a reluctant Luther must also face the ghosts of his own past. Striding back into the line of fire, he must choose who to protect... and who to sacrifice.
Whatever his next move, it will have devastating consequences for those around him - and will change John Luther forever.
Luther is produced by BBC Studios, the BBC's commercial production arm and co-produced with BBC America. Executive producers are Idris Elba for Green Door Pictures, Neil Cross, Marcus Wilson and Hilary Salmon for BBC Studios and Elizabeth Kilgarriff for the BBC.
Season 5 is produced by Derek Ritchie (Class, Doctor Who), directed by Jamie Payne (The Alienist, White Princess) and distributed by BBC Worldwide and co-produced with BBC America.
