Pilot
The perfect little town of Rosewood holds more than its fair share of secrets, and for four estranged friends, Aria, Spencer, Hanna and Emily, their darkest ones are about to unravel.
A year after their Queen Bee, Alison, goes missing, the girls begin receiving messages from "A", saying – and threatening – things only Alison would know. But it couldn't be Alison. Could it...?
The Jenna Thing
With Jenna's return to Rosewood, the girls are forced to face an unpleasant incident from their past that sealed their friendship forever, especially since "A" won't let them forget it.
Meanwhile, questions about the night of Alison's disappearance begin to arise, as the events of that fateful night continue to haunt Aria, Spencer, Emily and Hanna.
To Kill a Mocking Girl
The girls try to pay tribute to Alison's memory, but they are still being faced with unresolved issues. Aria has an unpleasant encounter with her father's former mistress, and Spencer must face a vengeful Melissa, while Hanna is trying desperately to get her boyfriend to forget the 'old Hanna'. But with "A" taunting them every step of the way, the girls will find that leaving the past behind is much harder than they first thought.
Can You Hear Me Now?
The girls block e-mails and text messages from all unknown users in an attempt to stop "A," but their problems are far from over. One girl receives a surprise visit, while another receives a gift from a prospective paramour. And just when things couldn't get any more complicated, the girls find out that trying to keep "A" away comes with a price.
Reality Bites Me
The girls must pay the penalty for trying to ignore ''A''. Whether it is a family in crisis, parental praise for an undeserved honor looming over their head or wearing totally unfashionable scrubs while working off a debt – the girls must deal with it all. And on top of that "A"'s lipstick message is still haunting them.
There's No Place Like Homecoming
While the homecoming decorating committee is knee deep in balloons, the four friends from Rosewood are just trying to stay afloat. Dealing with heartbreak, a boyfriend's virginity pledge and a vengeful sister all takes a backseat when one girl makes a shocking homecoming date choice that puts her in a possibly sticky situation.
The Homecoming Hangover
Spencer, Aria, Emily and Hanna must deal with the consequences of their disastrous homecoming dance. Family, friends and boyfriends are all in flux, and the girls need to act fast to prevent the situation from getting worse. To top it all off, they are also hiding killer information about Toby, and text messages from someone other than 'A' are causing tensions to rise in the Montgomery household.
Please, Do Talk About Me When I'm Gone
The girls are ready to say goodbye to Alison as her memorial service approaches. However, Alison's brother Jason shows up and the gang quickly finds out that saying goodbye is the last thing he wants to do. The clique wants to celebrate Alison's life in a peaceful and positive way, but with Detective Wilden back on the scene and Jason taking over the girls realize they may not have prepared for what is to come. Meanwhile, Emily and Maya go on their first date.
The Perfect Storm
Rosewood gets a massive storm on the day the students are to take their SAT test, which causes the school to postpone the examinations. Trapped in the school during the storm, the girls' personal lives become stormy as well. Drama strikes each girl differently and manifests itself into different situations. After the storm passes and the girls get to go home, they all come to the realization that taking the SATs would have been a much easier task to complete.
Keep Your Friends Close
"A" targets the girls once again as they attend an upscale camping trip for one of their friend's birthday party and they fear that "A" may want to crash the fun. The FBI becomes involved in Alison's murder case because of new evidence that they have found. Also, Hanna faces difficulties because of her financial situation.
