Sam and Dean go to Idaho to investigate some Enochian markings, and instead find themselves caught in a town overrun with demons. But the case goes farther south as the demons draw closer to discovering an unknown weapon, and the local hunter asking for their help proves to be an even bigger mystery than the town itself.

But over the years, a plot that begins with the murder of an acrobat's parents slowly evolves into a web of treacheries that forces Bruce to realize that he is just another piece on a board of higher powers.
