Sam (Jared Padalecki) and Dean (Jensen Ackles) investigate the death of Rabbi Bass (guest star Hal Linden, "Barney Miller"), who spontaneously combusted. The case becomes ever more confusing when they learn that the Rabbi was researching Nazi Necromancers. Sam and Dean are attacked by a Golem (guest star John DeSantis) who turns out to belong to the Rabbi's grandson, Aaron (Adam Rose). The key to the case lies with the Golem but Aaron doesn’t know how to control him, which leaves everyone in danger.
