As they try to pay tribute to Alison's memory, the four friends are faced with unresolved issues. With 'A' taunting them every step of the way, can the girls forge ahead and leave the past behind?

Tired of being harassed by 'A', the girls decide to put a stop to the anonymous emails and text messages by blocking all unknown users. But the friends' problems are far from over.

Trying to ignore 'A' backfired for the girls, and now they must pay the penalty. They must also deal with typical teenage drama - the boy kind.

The homecoming decorating committee is knee-deep in balloons, and girls are jockeying for position to be the queen, while four friends from Rosewood just try to stay afloat.

In the aftermath of the disastrous homecoming dance, the girls try to sort out the devastation that is left behind. If the little liars don't act fast, the situation could go from bad to worse.

After much planning, the day of Alison's memorial is around the corner, and the girls are ready to say their goodbyes. But their last-minute preparations soon get derailed.

A day of SAT testing is put on hold when a violent storm hits Rosewood, but the girls are stuck inside the school dealing with the drama that follows them everywhere.

The discovery of a new piece of evidence about Alison's disappearance brings the FBI to town, and the last thing the girls want to do is go 'glamping' for a birthday party.

Moments after Hanna is hit by a car, the girls' world is turned upside down. 'A' is no longer content to play a game of cat and mouse, and things take a far more precarious turn.

Hanna's return home from the hospital should be a joyous event, but being stuck in a wheelchair and feeling haunted by 'A' makes it feel more like a Hitchcock nightmare than a proper homecoming.

Relationships are in flux in Rosewood as the girls face many obstacles. As Noel steps up his pursuit of Ezra, Aria and Ezra begin to feel like there may be no way out.

As their doubts, fears and suspicions grow, Aria, Emily, Hanna and Spencer start to wonder what the true face of evil looks like. Is it the girl who will do anything to keep her loved ones near?

After a shocking revelation from the police, the spotlight is turned on four little liars who look to be crying wolf. But with everything pointing to Ian, how could the girls be wrong? Or could this be just another game "A" is playing with them? With the cops now demanding answers from Aria, Emily, Hanna and Spencer, will the girls come clean about "A," or are some secrets better left unspoken? Meanwhile, secret relationships take a toll on some of the Liars while others blossom. Love is not for the faint of heart.

As the heat is turned up on the suspicions surrounding Spencer, the girls must come to the reality that they aren't the only ones hiding secrets in Rosewood. Spencer remembers something that happened the night of the murder.

Everyone has something to hide - whether it be a secret romance, who they really are and what their true intentions are. For Aria, Emily, Hanna and Spencer, keeping things hidden is second nature, but having to live with those secrets can become a big burden. How long can Aria be with someone when they can't go out in public? Is it a true friendship when Spencer and Toby aren't able to be seen together? How truthful can Emily be when she can't be honest about whom she wants to be with? And how can Hanna move on when she secretly still wants to be with the one who broke her heart? With someone like "A" out there to watch their every move, four Liars may not have to worry about keeping things hidden for too much longer. Meanwhile, Rosewood police officer Garrett Reynolds is keeping his promise to keep a close eye on the girls - much closer than they realize.

Now that Aria, Emily, Hanna and Spencer are in possession of the information that Alison left them, the girls decide that it's time to finally put an end to "A" and the mystery surrounding their friend. But without certain proof that their hunch is right, how can the girls catch "A" in his/her own game?

Aria, Emily, Hanna and Spencer finally decide it is time to tell someone about "A". Meanwhile, Hanna's infamous grandmother drops into town for Tom's rehearsal dinner.

With the clock ticking and “A” calling the shots, the girls are sent on missions to do “A’s” bidding in order to save their trusted confidant. Each mission will ultimately lead to what the four liars want the most, but at a costly price to their loved ones and themselves. Can Aria, Emily, Hanna and Spencer go through with their given tasks in order to save one, or will they ignore “A” to save those around them from being hurt? And ultimately, will this matter when all is said and done? Nothing is ever as it seems in Rosewood, PA.

But when the girls decide to enlist Caleb’s hacking skills to help with their quest, Hanna no longer wants a part of the plan. The last thing Hanna wants is to get Caleb involved in something else shady and also to open the door to questions that Hanna can’t answer. Once the girls realize that “A” has a helper, Hanna has no other choice. Instead of focusing on figuring out who the “helper” is, Hanna decides to put all of her efforts into throwing a surprise party for Caleb. But will a surprise party at Spencer’s lake house be the diversion Hanna is looking for, or just a recipe for disaster? Meanwhile, Aria and Ezra must deal with the aftermath of coming clean.

With Lucas missing and questions surrounding what happened out on the lake, Hanna can barely catch her breath. With Caleb determined to find his friend, Hanna’s reluctance to help only causes more problems.

Meanwhile, Ashley continues her hunt to find answers about what is going on with Hanna with help from a surprising source.

Aria, Emily, Hanna and Spencer are on the quest for answers of what Alison knew before she died and they might have just gotten a big lead when someone from Alison's past appears.

And just when they feel like Duncan may be the only lead, Jason drops off a bag of Alison's personal items that could be more than just a bag of junk.

But would it be so bad if Hanna told Caleb that she needed to see Mona to get information about this "A?"

With Emily getting an insiders' view working the party, Aria working the crowd as a party-goer and Spencer staked out at the hospital, what could go wrong? The answer is - everything.

But is Aria ready to face her former tormentor, and more to the point, is Mona ready to give Aria the answers the PLLs are desperately looking for? Meanwhile, someone from Ali and Jason's past arrives in Rosewood and piques the girls' interest.

Emily is struggling to deal not only with the loss of Maya, but the knowledge that someone drugged her "that night" and how that has now affected Paige.

And what other secrets could she be holding onto? It's up to Mona to prove to the Liars if she has changed or not.

After the shocking events at the school marathon, Aria, Emily and Spencer are sure now more than ever that Mona is up to her old tricks.
