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" (glam-style camping) for a birthday party. But when they get a text that insinuates that "A" will be at the party, Spencer gets the idea that it may be their chance to finally put an end to the threats. Once at the camp party, however, not even the mani/pedi station can lift the girls' spirits when the evening takes a dangerous turn. Meanwhile, the Marin financial situation is pushing Ashley to the brink.

Hanna's return home from the hospital should be a joyous event, but being stuck in a wheelchair and feeling haunted by "A" makes her return feel more like a Hitchcock nightmare than a proper homecoming. Even though the girls try their best to support Hanna, they all have troubles they must face as well: Spencer is still reeling from Melissa's (recurring guest star Torrey DeVitto – One Tree Hill) surprise, when an unexpected roadblock is thrown up in her relationship with Alex (recurring guest star Diego Boneta – 90210, Mean Girls 2); Emily is hoping that an introduction to Maya during a tense family meal will smooth whatever apprehensions her parents may have; and blackmail is in the air as Aria and Ezra suspect a student is on to them.

In this episode, 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 thing take a far more precarious turn. More than ever, the four girls must turn to each other for support. With Hanna in the hospital and armed with the information of who "A" is, the girls backtrack to figure out how they got to this point. How could this person know everything? Meanwhile, each girl must also deal with a secret that is either discovered, confessed or confronted, proving that secrets still abound in Rosewood, Pennsylvania.

Jane is reunited with his former nemesis, Bret Stiles (guest star Malcolm McDowell) the charismatic cult leader of “Visualize,” when the head of an anti-cult activist organization is murdered. Louise Lombard (CSI: Crime Scene Investigation) guest stars as Nora Hill, a Dean at Visualize’s College.

Emily has been juggling a lot of secrets and lies lately and, when her father pays her a surprise visit before a big swim meet, the pressure gets to be too much, sending her to the hospital. But with the prospect of having to come clean to her father about Danby, Emily realizes she has bigger problems when “A” reveals a part in Emily's swim career. While visiting Emily, Spencer and Aria take the opportunity to try and do more digging around about the cause of Alison's death and how the broken field hockey stick may play a part in the last few moments of their friend's life. Meanwhile, Hanna struggles with the prospect of losing both men in her life when her father's "Save the Date" for his wedding arrives, and the possibility of Caleb (recurring guest star Tyler Blackburn) leaving Rosewood before his past can come back to haunt him.
