In the special Halloween episode, Aria, Emily, Hanna and Spencer crash the Ravenswood Founders Day Celebration after a clue in A's new lair suggests 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 (guest star Nicole Gale Anderson – Beauty and the Beast, Make It or Break It) along the way.
