Whilst attempting to save a group of Regents (after learning that Stukowski has been using artefacts to kill them), Pete and Claudia search for Stukowski's partner in crime and Artie and Myka find themselves trapped in a building that is disintegrating under the power of an artefact.

With the number of crazed, shivering, ravenous people on the rise, Myka and Pete investigate a zombie outbreak and determine the artefact responsible is a 19th-century mason jar. Back at the Warehouse, Claudia is spooked when a fortune-telling machine tells her that she is about to die.
