'Pretty Little Liars' Halloween Special Sneak Peek - Watch Now!

Want a sneak peek at the upcoming Pretty Little Liars Halloween Special?

Thanks to our pals at TVGuide, we’ve got one!

In “Grave New World”, Aria (Lucy Hale), Emily (Shay Mitchell), Hanna (Ashley Benson) and Spencer (Troian Bellisario) crash the Ravenswood Founders Day Celebration after finding a clue in “A’s” new lair that Ali may indeed be alive. Dressed in their finest Edwardian wear, the ladies hit the creepy cemetery party to find Ali before “A” can.

Tyler Blackburn, who leaves for Ravenswood in the episode, shared in the featurette below, “I think Ravenswood will appeal to a lot of different types of people and you don’t have to just be a Pretty Little Liars fan, because it has a supernatural element I think it’ll open up a whole new audience.”

“Grave New World” premieres Tuesday, October 22nd @ 8PM ET/PT on ABC Family.
