In the next episode of "Z Nation," Murphy (Keith Allan), Doc (Russell Hodgkinson), and the rest of the team stumble upon a barber shop where they encounter murderous zombies.

The trailer for the upcoming installment titled "Frenemies" was just released recently and showed Doc and Murphy preparing to get a haircut from a seemingly friendly barber. He motions them to sit in the barber's chair while Sketchy (Mark Carr) and Skeezy (Doug Dawson) watch from the sidelines. All of a sudden, when Doc sits in the chair, the demented barber turns a knob which fully reclines it. Doc then falls on his back as a trap door beneath him opens up and reveals a horde of murderous zombies in the basement. The terrifying creatures claw their way up to grab a hold of Doc who screams in terror.

It turns out that the barber shop is being run by a deranged group of individuals who lure unsuspecting people into getting haircuts and then feed them to zombies. Doc and Murphy try to fight back against their captors and even kill some horrific-looking zombies. However, they along with Sketchy and Skeezy, are then shown captured with guns pointed at them. "I tried to warn you," Sketchy says to them. "Well next time, try harder," Doc says in a frustrating manner. It remains to be seen if they will be able to escape the violent barber shop.

In the last episode, Murphy and the survivors came across an abandoned news station where they encountered a slew of zombies. They had to get to the roof in order to use the satellite dish so that they could communicate with Citizen Z (DJ Qualls). They were able to do so eventually.

"Z Nation" season 4 episode 10 will hit the airwaves on Friday, Dec. 1 at 10 p.m. EST on the Syfy channel.
