Overview

After trying to escape the dollhouse in the season five finale, Charles punishes Emily, Hanna, Spencer, Aria, and Mona, subjecting them to various types of torture while Alison, Ezra, Caleb, and Toby try to find a way to help find the girls. Andrew becomes a suspect after being reported missing. Realizing what Charles is planning to do with Alison, the Liars hatch a plan to get out of the dollhouse by setting his vault on fire. The plan worked successfully, and the girls get out of the dollhouse where they are met by Alison, Ezra, Caleb, Toby, and the police. Andrew is arrested and accused of kidnapping the girls. However, the girls are far from okay, as they all suffer from PTSD from their time in captivity. Another girl, Sara Harvey, who went missing the same time Ali did, is found in the dollhouse, reportedly having been held there for two years. Unable to deal with her home life, she runs away and stays with Emily for a while. Meanwhile, Ali tries to get answers out of her dad about Charles DiLaurentis, but he insists there is no one of that name in their family; however, Jason remembers Charles as his imaginary friend when he was a kid. Later, Andrew is released from police custody because of lack of evidence, and the Liars realize that he isn't Charles after all.

After discovering a photo of Mrs. DiLaurentis with Jason and another boy, Alison and Jason found out that they had an older brother that was, in fact, Charles. Kenneth explains that Charles tried to hurt Alison when she was a kid; he was subsequently admitted to Radley for diagnosis, and he died when he was 16. The Liars then searched Radley for answers, discovering that there was another person who visited Charles in Radley: Alison's great aunt Carol. Alison, Jason, Hanna, and Spencer later discover Charles' grave in her backyard. Meanwhile, Mona later returns to Rosewood, heavily questioned by the police about her actions while her friendship with Lesli is strained because of her involvement with Mona's actions. It is later revealed that Lesli was a former patient at Radley, and was roommates with Bethany Young, leading the girls to suspect that Lesli may be 'A'. Mona, however, tells them that Lesli is only pretending to be stable and that Charles faked his own death.

When the girls found out that Charles was coming to the DiLaurentis household (for his birthday), they plan on catching him as he is set to meet with Jason. However, the plan backfires when the police appeared. Rosewood High ultimately bans the girls from their prom and graduation after an incident at Aria's photo gallery contest. Hanna discovers that the company who gave her a scholarship is affiliated with Radley (and Mr. DiLaurentis). She and Spencer decided to return the money to the company, where they meet Rhys Matthews, whom they later suspected to be Charles. The girls also became suspicious of Aria's friend Clark, believing that he may be working for Charles when they saw him following Rhys into a warehouse. Despite being banned, the girls head over to the prom when they discover that Alison was meeting Charles there. Subsequently, Charles kidnaps Alison at the prom; the girls began searching for her, along with Ezra, Toby, Caleb, Sara, Mona, and Clark (who is revealed to be an undercover agent).

Working with Mona and Sara, the girls finally infiltrate A's lair, where they discover a live feed of Alison coming face to face with Charles, who is revealed to be CeCe Drake. CeCe then begins to explain her story and motives, revealing that she was born as Charles, but was not accepted by her father for believing she was a girl. She was sent to Radley, where she eventually transitioned into Charlotte. She also explains what led to Mrs. Cavanaugh's death at the hands of Bethany Young, her complicated relationship with Bethany and her subsequent death, the events regarding the night Alison disappeared, the deal she made with Mona, the events at the burning lodge, Wilden's death, the events in New York, and their mother's death. She explained that she did everything just to be closer to her family, and she became 'A' when she thought that the Liars were happy about Alison's 'death', so she wanted to make them suffer for it but couldn't stop the game because she grew obsessed with it. CeCe also reveals that Sara is both the other Red Coat and The Black Widow, working under CeCe's orders, leaving Emily distraught. CeCe heads for the roof to commit suicide (after her bomb attempt fails and Emily subdues Sara), but Alison and the girls convince her to stop, saying they now understand why she became 'A'. CeCe then surrenders and declares the game over. On Labor Day weekend, the girls say goodbye as they are leaving for college except for Alison who stays in Rosewood.

Five years later, as the girls have each pursued their own path and have started adjusting to a life without 'A', they are once again called back to Rosewood when Alison asks for their help for her sister Charlotte to be released from the psychiatric hospital. While the girls agree to help, Aria is the only who tells the brutally honest truth: she is still scared of Charlotte and doesn't want her released. Eventually, she is, only for her to be murdered the same night and then thrown from the church's bell tower. At her funeral, the girls are stunned to see Sara show up and begin to question her sudden appearance.

Sara starts stalking Emily. It is later revealed that on the night 'A' was revealed, after Emily punched Sara, Sara tried to stand up and put her hands on an electrical block, severely injuring her hands and making it difficult for her to touch or hold things. Eventually, a new 'A' rises, sending threatening messages with creepy emojis to the Liars, determined to get answers on the night Charlotte was murdered. Convinced that Sara is 'Uber A', the girls search for answers. Ali reveals that she and Charlotte's doctor, Elliott, are dating. Later they are married by Aria. The girls initially suspect Aria killed Charlotte. The suspicion shifts to Ezra and then Byron. Later, the suspicion shifts to Melissa when Spencer discovers Melissa's suitcase is broken with the missing part matching the description of the alleged murder weapon. Emily eventually finds it and is nearly run over by a truck and the driver steals the weapon. To save Ezra from losing his book deal with Aria's publishing company, she decides to write and submit some chapters for Ezra's new book. She's forced to tell him and they finish it together.

Emily is donating eggs to pay for school and loses her eggs when the clinic encounters a minor shutdown of its freezers; Aria gets burned by a fire caused by a malfunction at Hanna's bridal shower; and Alison falls down a flight of stairs. The girls build a plan of attack, which offers Hanna as bait. After Ali sees what appears to be her dead mother and Detective Wilden, she starts to question her sanity and checks herself into the same hospital Charlotte attended. Spencer, Toby and Mona work together to catch Sara, but instead they find old medical records for a woman named Mary Drake, and she was the one who gave birth to Charles while a patient at the Radley (now a hotel managed by Ashley Marin) 25 years ago, the DiLaurentis family adopted Charles as she was unable to take care of him.

The girls' plan is leave Hanna waiting for 'Uber A' to arrive at Lost Woods Resort, while Aria and the boys are out hiding, but when Hanna goes missing they find out that 'Uber A' used a secret passage and kidnapped her. Looking over footage from cameras outside, they all are shocked to see what looks to be Mrs. D, asking themselves how this is possible. At Alison's house, "Wilden" rips off his mask revealing himself to be Elliott, and Mary Drake, who is revealed to be Jessica's twin, joins him. They succeeded in committing Alison, and with Ali hospitalized, he has her money and the house as her husband, which is their revenge for what happened to Charlotte, as he was in love with her and Mary always felt an attachment as her birth mother. She glances at a photograph of Charlotte and says it is what she would've wanted. In the last scene, we see Hanna's unconscious body being dragged by 'Uber A' in the church's bell tower.
