The BBC have released the first full trailer for the upcoming fifth series of Luther.
Idris Elba returns alongside Dermot Crowley, Michael Smiley and Patrick Malahide also return as DSU Martin Schenk, Benny Silver and George Cornelius. Wunmi Mosaku (End of the F***ing World, Kiri) joins the cast as new recruit D.S. Catherine Halliday and Hermione Norris (Cold Feet, Spooks) will play Dr Vivien Lake, a psychiatrist who cares for some of the most vulnerable in society.
While the monstrous and seemingly indiscriminate killings become ever more audacious and public, Luther and new recruit D.S. Catherine Halliday played by Wunmi Mosaku are confounded by a complex tangle of leads and misdirection that seems designed to protect an untouchable corruption. But even as the case brings him closer than ever to the true face of evil, a reluctant Luther is forced to confront the unburied demons of his own recent 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 change John Luther forever.
Luther series 5 is coming soon to BBC One. Luther Series 1 – 4 are available on BBC iPlayer now.
