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 take viewers on a dark and emotional journey with turns at every corner.
