The fifth season of the American mystery drama television series Pretty Little Liars began airing on ABC Family on June 10, 2014.

[7] It was announced on June 10, 2014, that Pretty Little Liars was renewed for two additional seasons, making the show ABC Family's longest running original series.

[10][11] After Aria inadvertently kills the rooftop shooter, revealed to be Shana, the Liars try to adjust to the new world in which 'A' is presumably dead and Alison is very much alive, while still trying to keep up with Ali's new lie about her whereabouts over the last two years.

The friendship hits a breaking point when Ali has to identify her so-called "kidnapper", and the girls realize that Alison has lied to them the entire time she has been back.

Alison's trial ends with her being found guilty on Mona's murder, and subsequently, Aria, Spencer, and Emily are arrested as accessories.

After being kidnapped by 'A' on their way to the prison, Hanna, Aria, Spencer and Emily awaken in a dollhouse lair, with rooms designed to look like their bedrooms with surveillance.

Alison starts to reconsider her decision about coming home and the possibility of leaving for good, but Aria, Emily, Hanna, and Spencer are determined to keep her safe and to figure out who and what is behind this latest incident.

A connection between Bethany and Mrs. DiLaurentis links to Radley so the Liars begin their next plan as Aria volunteers to work there in order to get further information.

Also searching for answers, Spencer takes a note from Ezra's play book by borrowing some of his spy equipment to keep a closer eye on the home front, mainly on Melissa.

Hanna is the only one that is able to join Emily and Ali when Aria gets stuck in Radley and Spencer continues her mission by following Melissa's moves.

36 hours before, Spencer, Hanna, Emily and Aria ask Mona for help pertaining to the information that Alison confessed at the police station.

Holbrook's theory is that Spencer was so desperate that to make Alison keep her amphetamine abuse a secret, she had to kill Bethany Young.

Spencer and Mona implement a plan to get answers as they go undercover at Radley Sanitarium while Hanna and Caleb act as spies monitoring every surveillance to help the girls.

The Liars then arrive at the Dilaurentis' ice ball, where Ali makes a grand entrance, along with four unknown girls in masks.

As Hanna and Spencer leave the ice ball to find evidence, Aria spots Ali kissing a man in a Santa suit, who she believes is Officer Holbrook.

Spencer and Emily attempt to frame her by placing her hair at the crime scene, but in the process discover cameras that filmed the murder.

While continuing to bristle over Ted's marriage proposal, Ashley quits working for Jason DiLaurentis and tells him she's in a serious relationship with a pastor.

Spencer snoops through Veronica's briefcase and is unpleasantly surprised when she sees who's been visiting Ali on the prison's visitor log: Mike.

Emily confesses her feelings to Talia utilizing the machine designed to "catch whispers" that Spencer helped Jonny build at The Brew.

At the school blood drive run by Ashley, an incident with Mike worries Aria into believing that he is helping Alison, but refuses to listen to Spencer's allegations that he could be A. Emily is shocked to discover that Talia is married.

Determined to go to college and earn the tuition money her father won't give her, Hanna enters a beauty pageant to win the $20,000 prize and she recruits Emily as her dance coach.

Spencer has since forgiven Johnny for tricking her into painting the mural at Hollis, but when they discover that their "vandalism" has been put on display in a gallery without their permission, she assists him with some illegal work in order to get back their rightful artwork.

Alison's trial begins and the prosecutor exposes her kidnapping story as a lie to the court, making the Liars fear what else will be revealed.

When Hanna asks Alison about this she reveals that the messages started after her mother's body was found and she believed it was Mona because they stopped when she was murdered.

Spencer, Emily and Aria go to Mona's house and discover her room has been searched by 'A', but find a cryptic clue hidden in a mirror.
