After uncovering evidence that suggests “A” is hiding out closer than realised, the Liars step up their investigation into their most recent suspect. Hanna continues to crumble.

An intriguing riddle from “A” has the Liars hitting the road and heading to Ravenswood, where they are surrounded by some familiar faces.

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.

The presence of Mrs DiLaurentis continues to unnerve those around her, especially when she gives Hanna a parrot, whose gift for mimicry provides an insight into Alison’s last days.

A battle of the brains stresses Spencer, Aria learns of reasons to suspect her father of foul play, Hanna confronts Lucas, and Emily gets a fright in the woods.

Ailing Aria has reason to be afraid, while Spencer’s romantic gesture results in an unpleasant surprise.

Distracted Spencer’s anger is let-loose on Ezra, hurting Aria. Emily and Hanna each end up at the police station.

Emily’s memories get muddled in therapy, Caleb’s boyhood things intrigue Hanna, Ezra’s brother brings trouble, and Spencer gets bitter.

Spencer’s misbehaviour causes concern, Hanna engineers an encounter Caleb is resisting, Emily’s detective work turns dangerous.
