　　Filming has started on BBC Two’s critically acclaimed drama The Last Kingdom, from Carnival Films. The second series, adapted by BAFTA-nominated and RTS award-winning writer Stephen Butchard from Bernard Cornwell’s bestselling series of novels, is to return to BBC Two next year, with Netflix joining as a co-production partner.
　　The emotionally complex and compelling landscape of revenge, rivalry, hostility, corruption, love, sex, loyalty and friendship, forms the backdrop to a gripping adventure based on Cornwell's novels, The Lords Of The North and Sword Song – part of the hugely popular bestselling franchise The Last Kingdom.
　　Set in the year 878, the second series returns as fearless and instinctive warrior Uhtred continues his fight for his native land of Northumbria. Uhtred, having given his sword to King Alfred, despite his upbringing by the invading pagan Danes, embarks on his voyage north to reclaim his own fate: to avenge Earl Ragnar’s death and recapture his ancestral lands of Bebbanburg.
　　Alfred’s conviction to create a united England is stronger than ever, and he sets his sights on the wild lands of the north, which have fallen into chaos and rebellion. It is a dangerous time for Saxon and Dane alike, but Alfred champions a new king - a Christian Dane - to unite the tribes. However, this king has been enslaved, and Uhtred becomes embroiled in a rescue mission, which brings him face to face with an enemy of old.

　　年轻勇士Uhtred的亲生父母均死于入侵者维京人之手，而年幼的他被维京人抚养长大。为了夺回亡国故土，他游走于敌对双方之间，踏上了危险的征程。 第三季中，Alfred大帝油尽灯枯，但他依旧没有放弃统一英格兰的梦想。Uhtred临危受命迎战新敌人——丹麦战神Sigrid。而老王日薄西山、国家腹背受敌之际，继承人Aethelwold却对王位毫无兴趣，权力更替困难的真空期似乎是Uhtred不可错失的好机会……可他会背叛Alfred大帝吗？
