Christopher has a secret to share, one that he entrusts with his favourite comedian. When Christopher ends up dead soon thereafter, what's Leo to do but act on the information he's been given, even if it's completely insane? Setting out to find the mysterious town named Elswich, Leo can't deny there's something off about the entire thing. For one thing, the community of the town doesn't seem normal.
US Marshal Virgil Bone finds himself amongst the Isle's isolated community - a community that shares a horrific past that still taints their daily life.

Now he's stranded, surrounded by secrets and a rising death toll. If only he wasn't met with aggression, then maybe he could help save lives.
