Pretty Little Liars Season 4 Halloween Episode Promo: The Search For Ali Is On! (VIDEO)

Forget "A!" When Pretty Little Liars Season 4 returns in October, it's all about Ali. Now that the Liars know Ali is alive, they're on the hunt to find their friend. But with Ezra now lurking in Ravenswood, does Ali want to be found? It looks like we're going to have to wait and find out, Pretty Little Liars fans.

Until then, here's the official synopsis for the Season 4 Halloween special (Episode 13 — “Grave New World"):

"Aria, Emily, Hanna, and Spencer 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. But if Ali is truly alive, could the PLLs be leading “A” straight to their friend without knowing it? With Ezra lurking in the shadows, “A” may be closer than the girls realize.

Meanwhile, Caleb heads to Ravenswood to help the girls and meets kindred soul Miranda (Nicole Gale Anderson) along the way."

Catch the Pretty Little Liars Season 4 Halloween special on Tuesday, October 22, 2013 at 8 p.m. ET/PT on ABC Family.
