The CW has released a sneak peek clip from next week’s episode of Supernatural, titled “Everybody Hates Hitler,” which involves the reveal of a spoilery new set.

In the previous episode, Sam and Dean were given the coordinates and a key to a bunker belonging to the Men of Letters, a group of men who collected information on the supernatural and shared it with elite hunters. The group, of which Sam and Dean learned they are legacies on their father’s side, became extinct when the last survivor was killed in “As Time Goes By.”

At the end of the episode, Sam and Dean decided to look for the bunker, and in this preview clip, they’ve found it.

According to executive producer Robert Singer, the bunker will become kind of a home base for the boys…for quite some time. He describes the bunker set as “really stunning,” which we can see from the final few seconds of the clip.

Outside of the brothers discovering their new home base, this episode will feature Sam and Dean hunting a Golem after they investigate the spontaneous combustion of a Rabbi.

In the investigation, “they learn that the Rabbi was researching Nazi Necromancers.” The Golem “turns out to belong to the Rabbi’s grandson, Aaron. The key to the case lies with the Golem but Aaron doesn’t know how to control him, which leaves everyone in danger.”

We also have the promo for the episode, featuring the Golem:

“Everybody Hates Hitler” airs Wednesday, February 6 at 9:00 p.m. ET.
