In Columbus, Ohio, an elderly woman attempts to buy an antique pocket watch only to be murdered along with the owner of the antique store by the Thule Society, an organization of Nazi necromancers. They later begin chasing a young woman named Ellie Grant. The murders draw the attention of the Winchesters who learn from a young Thule member named Christoph that the watch holds the soul of Adolf Hitler and the Thule intend to use Ellie to resurrect Hitler. The Thule succeed in abducting Ellie and resurrecting Hitler in the body of the Thule leader, but Christoph aids the Winchesters in finding the Thule. Ellie and the Winchesters kill the Thule High Command and Dean kills Hitler. After burning the bodies of the Thule, Ellie finally stops running from everything while Christoph is forced on the run from what's left of the Thule Society.
