Set in the Yorkshire Dales in the 1870s, the drama will focus upon the shantytown of Jericho, home to a community that will live, thrive and die in the shadow of the viaduct they've been brought together to build. Rough, rustic and remote, yet with a wild west, carnival atmosphere, Jericho is a community of pioneers, settlers and outcasts, people with secrets to hide and those looking to start again.
