Idris Elba's 'Luther' Return Gets December Premiere: Our Wish List

BBC America has finally announced the plot line for the one-night, 165-minute event. It begins with Detective Chief Inspector John Luther — last seen tossing his trademark jacket into the Thames and walking away with killer/confidante Alice Morgan (Ruth Wilson) — on a leave of absence. He’s “laying low in a rundown cottage” when he receives visitors, new faces DCI Theo Bloom (Darren Boyd) and DS Emma Lane (Game of Thrones’ Rose Leslie), who come with "a shocking piece of news that draws him back to London in search of the truth.” Meanwhile, a cannibalistic serial killer (John Heffernan) is terrorizing the city, “eating body parts as he goes.” Detective Superintendent Unit Martin Schenk (series stalwart Dermot Crowley) and his Bullpen need to connect the dots between the victims.
