Yorkshire, 1874. Penniless following the death of her husband, Annie Quaintain and her two children are turfed out of their village home and forced to start a new life in Jericho, a remote shanty town in the expansive and rugged Yorkshire dales. Jericho is home to a community of navvies and pioneers, prostitutes and vagabonds who will live and die in the shadow of the viaduct they've been brought together to build. Rough and rustic, yet with a wild west, carnival-like atmosphere, it's a place where people with secrets can hide, and where love can flourish against all odds. Set against a visually striking frontier landscape, this epic, eight-part drama series follows the creation of a community from nothing and the human stories and heroic struggles of survival that emerge.
