In the next episode of "Z Nation," Roberta Warren's (Kellita Smith) visions and dreams lead the group back to Mercy Labs where they have been previously.

The sneak peek and promotional photos for the upcoming installment titled "Return to Mercy Labs" were released just recently and they show Warren together with Murphy (Keith Allan), Doc (Russell Hodgkinson), 10K (Nat Zang), and Sgt. Lilley (Gracie Gillam) walking in a barren field heading toward the east.

Lilley and 10K start talking about how following Warren will lead him back to his girlfriend. However, when Warren reaches a ledge, she notices that the building in their way is the dreaded Mercy Labs. "Oh crap! Not this place again," Murphy says to them in frustration." Lilley asks what the problem is which prompts 10K to reply, "We've been here before."

They all stand on the cliff overlooking the laboratory as they prepare to head for the building. "Warren, why the hell did you lead us back here?" Murphy says to her with exasperation. The leader keeps walking straight as she replies, "I don't know but I intend to find out." Apparently, Warren's visions have led her back to this place where they barely escaped a couple of months earlier. It seems that the leader has to perform a dangerous task there, but she has no clue as to why she must do it.

In the last episode, Murphy and Doc came across a barber shop that was overlooked by two crazy people who liked to trap visitors in their basement of zombies. With the help of Sketchy (Mark Carr) and Skeezy (Doug Dawson), they were able to overpower the insane couple and get to safety.

"Z Nation" season 4 episode 11 will hit the small screen on Friday, Dec. 8, at 9 p.m. EDT on the Syfy channel.
