The BBC has today released promotional pictures for the last episode of River.

John River (Stellan Skarsgrad) is a brilliant police officer whose genius and fault-line is the fragility of his mind – a man haunted by the murder victims whose cases he must lay to rest. A man who must walk a professional tightrope between a pathology so extreme he risks permanent dismissal, and a healthy state of mind that would cure him of his gift.

Following her recent Emmy-award win for best ‘Writing, Miniseries or Movie’ for BBC Two’s The Hour, Abi Morgan says of her new series:

“River is a fractured mind navigating a brutal world. And he does it wearing a police badge. I can’t think of a better home for it than the BBC. The chance to tell big stories in a bold way on a channel that embraces so many writers, directors and actors I admire and respect is a huge treat.”

Nicola Walker (Last Tango In Halifax) plays River’s colleague and confidant, Detective Sergeant Jackie ‘Stevie’ Stevenson, with Adeel Akhtar (Utopia) as Detective Sergeant Ira King. Lesley Manville (An Adventure In Space And Time) will play their superior, Chief Inspector Chrissie Read. Eddie Marsan (Ray Donovan) also joins the cast as a notorious killer who haunts River.

The fifth episode is set to be broadcast on Tuesday the 17th of November from 9:00pm to 10:00pm. Below are more promotional pictures as well as the synopsis for the sixth episode.

River is convinced that Stevie’s investigation into the exploitation of undocumented migrants holds the key to her murder. Further questioning of someone close to the team reveals a system of immigration cases that could lead into some very unexpected places. When a common link to certain businesses is found, it all starts to fall into place for River, with unfortunate repercussions. As Stevie’s loved ones reel from the truths unearthed, River holds the future in his hands. How will he keep his final promises to Stevie? How can he keep her secrets for her and do what is right? And, if he solves her murder, can he cope with losing her forever?
