The truth may be only one text away in this one-hour series filled with mystery, scandal, intrigue and nail-biting suspense. Based on the best-selling book series for young adults from Alloy, PRETTY LITTLE LIARS is set one year after the disappearance of Alison, the manipulative and vindictive queen bee. The drama revolves around four 16-year-old girlfriends - Aria, Hanna, Spencer and Emily - who have lost touch with one another until each begins to receive mysterious messages suggesting Alison is watching them and knows their most private details they had hoped to keep hidden. Suddenly, living in their picturesque suburban community is far from perfect as secrets, lies and betrayals threaten everything they hold dear.
Meet the Pretty Little Liars. There's Aria Montgomery (Lucy Hale), Spencer (Torian Bellisario), Hanna (Ashley Benson) and Emily (Shay Mitchell). When their best friend Alison (Sasha Pieterse) goes missing they begin receiving text messages from an person known as 'A' who is planning to reveal all their secrets which only Alison knows. They quickly begin to suspect Alison is the one behind the text messages but they might have the wrong person. Other characters include Ella Montgomery (Holly Marie Combs), Byron Montgomery (Chad Lowe), Melissa (Torrey Devito) and Pam Fields (Nia Peeples).
The circumstances around Ali’s disappearance continue to haunt Aria, Emily, Spencer and Hanna as questions arise about the night she went missing. To complicate matters, Jenna Cavanaugh’s return to Rosewood makes the girls face an unpleasant past and an incident that sealed their friendship forever. Can the girls face what has taken place, especially since “A” won’t let them forget?
The saying “The past will come back to haunt you” is never more true than for Aria, Spencer, Hanna and Emily. As the girls try to pay tribute to Alison’s memory, the four friends are faced with unresolved issues. Aria has an unsettling encounter with Byron’s old mistress, Meredith. Emily is forced to see Toby Cavanaugh in a new light. Spencer is reeling in the wake of a vengeful Melissa. And Hanna is desperate to have her boyfriend Sean forget the “old” Hanna. With “A” taunting them every step of the way, how 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 e-mails and text messages by blocking all unknown users. But just because the mysterious ghost isn’t looming over their heads, the girls’ problems are far from over. With a surprise visit by a father, a surprise gift from a prospective paramour, getting some unwanted advice and an unwanted scholarly accolade – the girls’ lives continue to get more complicated by the day. And after dealing with all of that, do the Pretty Little Liars really think they could keep “A” away forever?
Still reeling from the haunting message scrawled across Spencer’s vanity, the next morning the girls discover an additional, even spookier message from “A” – this one in the form of a video that was clearly recording them from the vantage of Spencer’s closet. As a penance for crashing Sean’s car, Hanna is forced to take a filing job in his mom’s office; there, she discovers that Jenna has been seeing a psychiatrist in the same building. After finding out that Sean’s been hanging out with another pretty little blonde, Hanna decides to keep close tabs on Sean by joining his abstinence club at school, “Real Love Waits.” There, she finds a surprising ally in the equally reluctant Lucas, a nerd that was a former target of Alison’s taunts.
Hanna, Spencer, and Emily arrive at Aria’s to console her with junk food and rag mags – thinking she’s sullen from her father’s affair being revealed to her mother by “A,” when in fact she’s bruised from her tiff with Ezra. The next day, Spencer urges Hanna to try and steal Jenna’s file from the psychiatrist’s office that’s in the same building as where she works, certain that it contains the key to the identity of “A,” or at the very least what the Cavanaughs are hiding.
Aria, Hanna and Spencer mistake Emily’s wounds for an attack by Toby, and quickly inform her of his sordid past with stepsister Jenna to keep her from contacting him again. Later, still recovering from her head trauma, Emily awakes to find a surprise visitor: Jenna, who begins to threaten and grill her with questions about her stepbrother’s whereabouts. The girls, sans Emily, head toward the shed to hide Toby’s file that Hanna stole, but in a panic, Aria decides to throw it in the river instead – moments before Emily finally gets through to their cell phones pleading not to destroy it. Oops!
As Aria, Spencer, Emily and Hanna begin to prepare for Alison’s memorial, they must contend with Alison’s older brother Jason arriving in Rosewood a changed man – the formerly gawky and gothic outsider is now as polished as a preppy politician, and he’s got plenty of plans for the memorial of his own.
A huge storm is on the horizon, as Aria, Spencer, and Hanna study in preparation for the SAT exam the next morning. Emily is nowhere to be found, though. Where’s she at? Well, later Emily arrives home, soaking wet, covered in mud, and crying.
A new piece of evidence leads the police to officially announce that Toby Cavanaugh is wanted for the murder of Alison DiLaurentis, though Emily, Spencer, Aria and Hanna have their doubts they’ve nabbed the right suspect.
Aria, Spencer, and Emily are left unraveled after Hanna is hit by a car, presumably driven by ―A, the night of Mona's glamping party.
The girls wheel their helpless friend Hanna back into her home, where she‘ll be on bed rest for a few more days before returning to school. There, Hanna quickly discovers the wads of cash that Ashley‘s been hiding from her mini-heist, which her mother plays off as a “loan.”
Aria grows increasingly suspicious of Mike‘s burgeoning friendship with Noel, especially when Mike tells Byron and Aria at the dinner table, rather unwittingly, that Noel has been spreading a rumor about Mr. Fitz being with one of his students. Ezra is ready to resign from school to protect his relationship with Aria, but not before “A” swoops in and shockingly saves the day – framing Noel for cheating on exams.
The girls examine the video “A” left for them that illuminates what looks to be the final moments of Alison’s life by the Kissing Rock the night she disappeared; right after Ian‘s cameo on the video, he surprises them in person as he tries to grab a late night snack from the Hastings kitchen – as it‘s become more clear than ever that danger is always just around the corner in Rosewood.
The Pretty Little Liars still try and brainstorm what the picture “A” left them means, as Spencer goes to seek out Jason DiLaurentis, who‘s once again hanging around Rosewood. Jason tells Spencer that he‘s received the same photo she has of Alison the night she disappeared, and goes on to tell her that a private investigator has cleared it as a fake.
Soon after discovering that someone is making it look like she bought the beaded bracelets, Spencer takes a sudden interest in helping tutor Toby, who is still under house arrest. When Spencer shows up to tutor Toby, he cryptically asks her to leave, but not without leaving her with an even more cryptic message written in Braille in the book she lent him.
Aria, initially hurt by Hanna’s betrayal, learns to forgive her when she realizes they’re both contending with a more evil power in “A,” who’s clearly trying to tear them apart. Meanwhile, After discovering that he’s been staying at Rosewood High, Hanna invites Caleb to secretly crash in her basement, leading to both a burgeoning, unlikely friendship between the two and raised eyebrows from her best friends.
As if Aria, Hanna, Spencer, and Emily don‘t have enough drama in their lives, Mr. Fitz decides to put on a school production of the award-winning play The Bad Seed, the story about a girl who wreaks havoc on her small town – eerily echoing our Pretty Little Liars’ own troubles. The girls urge Aria to be Ezra‘s stage manager for the production, which backfires when the two prove to have an uncomfortable, awkward working relationship. Meanwhile, after seeing both his wife and daughter take a liking to Mr. Fitz, Byron asks him out for a drink, where the two begin to form a common bond over literature.
The girls realize they‘ve been duped when the bloody trophy lands them in hotter water than expected, with an angry police team more hell-bent than ever to find Alison‘s killer, despite these setbacks. Further complicating matters is Garrett Reynolds, a boy the girls all knew growing up in their neighborhood, who‘s a police officer now that‘s just been assigned to the case. Back at the Hastings residence, Ian deftly turns the tables on Spencer by taking the spotlight off himself and placing it on her recent, erratic behavior – which has become a growing concern for her family.
Spencer is shaken when the investigation that’s focused on her leads to the police searching her home. But despite all of her troubles, she continues to form an unlikely friendship with Toby.
As the town prepares for the annual Founder’s Day festival, Spencer’s family urges her to make a public appearance after the cops’ search warrant. But they also don’t want her to see Toby anymore!
In the spring finale, the girls come together to finally uncover Alison’s killer and the identity of “A” – but things don’t go according to plan…putting all of their plans – and lives – in jeopardy.
