In the season three premiere, as the second anniversary of Alison's disappearance nears, Aria, Emily, Hanna and Spencer are thrown back into turmoil after a shocking night.

Aria, Emily, Hanna and Spencer think Jenna's (TAMMIN SURSOK) birthday party could be the perfect setting for "A" to strike - and for them to catch their tormentor.

A new clue could lead the girls down the wrong path. Emily gets another flashback from "that night," leading to a surprising suspect, and Aria questions Ezra's new influx of cash.

When things look dire for Hanna, the girls turn to Mona to help their friend out. Plus, someone from Alison and Jason's (DREW VAN ACKER) past arrives in Rosewood.

Trick or treat? The Rosewood Halloween Ghost Train becomes one killer party in this special Halloween-themed episode. Plus, Adam Lambert performs.

Holding new information about Detective Wilden (BRYCE JOHNSON), Aria, Emily and Hanna are on the hunt for answers about the detective's past. Spencer finds someone to lean on.

Spencer is now ready to talk, but Emily is not ready to accept what she has to say. Hanna helps her mother and keeps a new secret, and wonders if "A" had something to do with it.

Aria, Emily and Hanna try to locate a missing Spencer - but Spencer may not want to be found. Emily meets Olympic gold medalist MISSY FRANKLIN (guest starring as herself).
