Spencer is reeling in the wake of someone with a vengeance and Hanna is desperate to have her boyfriend forget the "old" Hanna. With "A" taunting them every step of the way, can the girls forge ahead and leave the past behind? Meanwhile, Detective Wilden (recurring guest star Bryce Johnson – Popular) uses his new connection to Hanna and Ashley to his benefit. But will he get the answers he's looking for by making himself at home in the Marin household?

Will the girls be able to protect one of their own or will the evening turn out to be a night they can never forget?

What happens to one little liar when parent-teacher conferences come around and her father sits face to face with the love of her life? What about when another one reaches out to a tarnished innocent, when nobody else will? And what about the liar who is taken by surprise by an unpleasant person? Lastly, don't forget about the liar who is getting way too comfortable with someone she might not want to trust. Whatever the situation, "A" is certain to have something to say about it. Oh, just another normal day in Rosewood, PA, for Aria, Emily, Hanna and Spencer.

With Lucas (recurring guest star Brendan Robinson) missing and questions surrounding what happened out on the lake, Hanna can barely catch her breath. Caleb (recurring guest star Tyler Blackburn) is determined to find his friend, but Hanna’s reluctance to help only causes more problems. Can Hanna really tell Caleb what happened in the boat without tipping him off to her larger “A” problem? And if she did tell him, would he be willing to stick around after hearing all the horrible things Hanna has done? Meanwhile, Spencer follows a lead about “A” which guides her to an unexpected place and revelation.
