Overview

Picking up the night Ian Thomas's body disappears, Spencer, Aria, Hanna, and Emily are painted as liars by the news and police. The girls' parents request they see a therapist, Dr. Anne Sullivan. They initially refuse, and after a tense therapy session, their parents ask that the girls end their friendships with one another. This creates much tension, as the girls are forced to meet in secret. Spencer reveals that Ian may still be alive, suspecting Melissa to be hiding him somewhere. With the help of Melissa's ex-fiancé Wren, the girls follow them out to an old silo, where Ian's body is discovered, along with a suicide note. Emily later realizes that the note is composed of various messages from "A" and that "A" planted the note to make them think Ian had murdered Alison. Armed with this revelation, the girls begin investigating other potential suspects, such as Alison's older brother Jason, who has moved back to town, as well as Jenna Marshall. They later cut ties with Garrett Reynolds after learning of his romantic relationship with Jenna, who Ali had accidentally blinded in a prank gone wrong.

The girls confess to Dr. Sullivan that they are being tortured by "A", allowing Dr. Sullivan to piece together the blackmailer's identity. However, before Dr. Sullivan can inform the girls of who "A" is, she disappears. "A" forces the girls to do various tasks throughout Hanna's father's wedding day, such as forcing Aria to blackmail Ezra's former fiancé with a plagiarized college paper and sabotaging Hanna's father's wedding. Spencer is also forced to end her relationship with Toby Cavanaugh to keep him safe from "A's" wrath.

Emily is lured out to an old barn, where she is trapped by "A" who attempts to kill her using carbon monoxide poisoning. However, someone rescues her, and Emily has a vision of Alison. The girls arrive and "A" instructs them to dig up Dr. Sullivan before she runs out of oxygen. However, "A" has framed them, and they are subsequently arrested with the shovel Alison had been murdered with. Spencer's mother is able to get them out of jail and they are forced to endure community service.

Aria also reveals her relationship with Ezra to her parents before "A" can, which ends negatively. Aria's father makes numerous threats towards him, before causing him to lose his job at Hollis College. Although they break up briefly, Aria and Ezra begin seeing each other in secret with the help of her childhood friend, Holden Strauss. Unbeknownst to his overprotective parents, Holden participates in regular fighting competitions, despite having a severe heart condition.

The girls later attempt to trick "A" by making them think they have something that could give away their identity; Emily is confronted by "A" in an abandoned plant nursery. When Emily reveals the girls had tricked them, "A" physically attacks her, but Aria and Spencer arrive and corner them. They throw a vase into the air, shattering the glass ceiling and allowing them enough time to escape; however, Hanna arrives and hits "A" with her car, knocking them down momentarily. The girls chase them into the woods, but lose them. When they examine Hanna's car, they discover "A's" phone on the ground, which had apparently fallen out of their pocket when Hanna hit them with her car. The girls enlist Caleb's help in unlocking the phone, as Hanna and Caleb had gotten back together during the later half of the season.

Eventually, Alison is linked to an old doll hospital in town nearby called Brookhaven, and later a rural motel, The Lost Woods Resort. The girls attend a masquerade party, where they plan to confront "A" who appears to be a woman dressed as The Black Swan from Swan Lake. Spencer, accompanied by Mona, rides out to Lost Woods, while the other girls chase "A". Spencer and Mona are able to steal the key to one of the rooms, which is revealed to be "A's" Lair. Mona then reveals to Spencer that she is "A", while the woman at the costume party was only a decoy. Mona knocks Spencer unconscious, driving her to a nearby cliff. She gives Spencer the option of joining her "A" Team, or dying.

Spencer momentarily escapes, and the other girls learn of Mona's plan and rush to her aid. Spencer and Mona struggle, and Mona is knocked into a ravine, but survives. Emily learns that Maya was murdered, after she had seemingly disappeared. Mona is hospitalized in Radley Sanitarium, where she is visited by a blonde woman in a red trench coat, revealing Mona was working for someone else the whole time.
