ABC Family aired Pretty Little Liars Halloween special called "Grave New World." If you haven't seen the new episode you can check it out down below before I continue with the episode recap.

Aria, Emily, Hanna and Spencer decide to crash the Ravenswood Founders Day Celebration after finding a clue in "A's" new lair that Ali may be alive. Dressed as Edwardian the girls make their way to the cemetery party to find Ali before "A" does.

The girls were warned to leave Ravenswood, but they ignored the threat and decided to stay in hopes to find Ali before "A" does. Seeing Ali after what seemed like an eternity freaks Emily out.

Vowing to keep their boyfriends out of it the girls figure things out on their own, but it doesn't take long for Caleb to follow their trail after Toby failed to help back Caleb up he decided to make his move to Ravenswood by himself.

Caleb runs into a girl named Miranda who says she ran away from her foster home. After extending a helping hand Caleb, Miranda quickly turns Caleb down.

Ezra tries calling Aria, but she only reveals to him that she is in Ravenswood, but she doesn't know she just told the "A" her location. The former den mother tells Emily that staying in Ravenswood isn't a smart idea.

The girls end up split up, but when they come back together they spot who appears to be Ali running out of the cemetery. They follow her into a crypt where she then disappears leaving the girls wondering if they are imaging things or if "A" moves that quick.

The girls get trapped inside the crypt and as cliché as it is, no one has signal on their cells. As the girls search for a way out a blast of wind comes and the power goes out. When the lights come back on Hanna is gone.

Hanna now separated from the crew tries to find her way back to them when all of a sudden she finds a note on the walls written in blood that says, "Help Me." Hanna manages to find a way out through one of the tunnels and ends up inside a house, with "A" right on her heels.

Caleb and the new girl Miranda finally arrive in Ravenswood, but they soon split ways. Caleb goes to find his girlfriend. Randomly Miranda sees Hanna first and it is Miranda's uncle's house that she is now in. Miranda was the one who released Hanna from the phone booth. When Mirada asks for an explanation as to what is going on Hanna says she doesn't have time to explain Ali or "A."

The rest of the crew shortly found themselves inside Miranda's uncle's house and Spencer is the next one to go missing, but what doesn't make sense is that if "A" was on Hanna's heel then who took Spencer?
