Acclaimed writer Hans Rosenfeldt continues his first British drama following the international success of the Swedish/Danish series `The Bridge'. Anna Friel stars in the lead role of Marcella Backland, a British police detective working in contemporary London. Set in Rosenfeldt's unique style of Nordic Noir, the body of a missing child is discovered inside a wall and a task-force is assembled to catch the killer. A complex set of characters from all walks of life and interweaving storylines will take viewers on a dark and emotional journey with turns at every corner.
