Set in the Yorkshire Dales in the 1870s, the series focuses upon the shanty town 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. Jericho is a community of people with secrets to hide and those looking to start again.

When one of a group of friends downloads the mysterious Red Rose app, plans change. What starts innocently as a game of admiration rapidly descends into something much darker.
