(There are Spoilers) John Strange and his girlfriend Nurse Jude Atkins,Richard Coyle & Samantha Janus, get caught up with this mysterious disease-Bone Fever-that seems to arrive on the scene together the arrival of this strange headless coachman. I'ts the coachman's job to takes those who succumb to Bone Fever to their final resting place.
Canon Black, Ian Richardson, Strange's former boss at the Church, before Strange was defrocked, has a good idea of where and when Bone Fever will again strike the local population. But he's stymied by Dublin University graduate student Randolph Mason, Jack Broder, who's researching the mystery behind this Bone Fever and how it originated. Mason's snooping around the cathedral will in the end release the dreaded Bone Fever with him becoming it's first victim!
Strange himself had come across Bone Fever some time back when he was still a minister in the church. It was that event in his life that changed it forever in him ending up defrocked and becoming, by his obsession with demons among us, a full fledged demon hunter. Now with Bone Fever, which we later learn is connected to an evil Irish Banchee, about to break out again Strange feels he has a second chance to redeem himself. In the fact that the last time he faced the dreaded Banchee Demon he not only failed to save a number of its victims but himself, by still caring scares from that deadly encounter, as well!
The movie gets a bit confusing with it going back and forth in time in how the Otterman Family were involved with the deadly Bone Fever back in 1908. It's only when Liam, Claran McMenamin, a local taxi driver shows up on the scene that we the audience, together with John Strange and Jude Atkins, get to finally know the truth about the Demon behind the dreaded and almost 100% fatal Bone Fever. And not only the Demon's connection to the death coach but even more shocking who, it its human form, it's secret identity really is!
