The episode, directed by Melanie Mayron and written by Maya Goldsmith, originally aired on February 18, 2014 on ABC Family. In the episode, Spencer is ready to tell Aria that Ezra is "A", while Hanna and Emily, worried that Aria will be hurt, remain hesitant. Meanwhile, Spencer’s addiction to amphetamines is exposed, causing damage to her credibility among the Liars.

“Free Fall” yielded 2.56 million viewers and a 1.0 demo rating, up from the previous episode. It received highly positive reviews from contemporary critics, with the performances of Bellisario and Hale receiving widespread acclaim, as well as praise for the episode's dialogue between Ashley Benson and Shay Mitchell’s characters, drawing comparisons to Rosencrantz and Guildenstern.

Spencer (Troian Bellisario) is eager to tell Aria (Lucy Hale) that Ezra (Ian Harding) is “A”, but Hanna (Ashley Benson) and Emily (Shay Mitchell) are not sure when the best time is. After catching Spencer in his classroom in her pajamas, Ezra tells Aria about Spencer’s addiction to amphetamines as well as a previous incident involving them. She tells Hanna and Emily and they all hold an intervention at Spencer’s house. When confronted with the truth, Spencer breaks down and confesses that Ezra is “A” while continuing to deny the truth.

Spencer tries to explain to Hanna and Emily the inconsistencies she discovered in Alison’s journal, which leads to a plan to lure Ezra out of obscurity using a bag of money for Ali. Hanna and Emily meet at Ambrose Pavilion to catch Ezra and wait for Spencer to arrive, who is supposed to be dressed as Alison. Someone dressed as Alison arrives and the girls assume its Spencer. Spencer comes later and the girls realize it was "A", not Spencer. They attempt to follow the girl but she runs off and the room’s lights start short-circuiting. As the girls are about to leave, Emily notices the bag and takes it, while Hanna notices a blonde wig in the trash.

Aria tells Ezra about the intervention and he lets slip some information that Aria did not share with him, causing some suspicion. She later goes to his cabin, where she finds his manuscript detailing the lives of all the girls, including Alison. She runs off into the forest, trying to hide from Ezra, and eventually boards a ski lift. Ezra catches her as the lift is about to go and tries to explain everything. Aria, in disbelief, threatens to expose the manuscript but Ezra knocks it out of her hands.

Meanwhile, Mona (Janel Parrish) and Mike (Cody Christian) continue their relationship, but Mona struggles to keep her past behind as Ezra continues pressing her for help. Veronica (Lesley Fera) and Toby (Keegan Allen) discovers Spencer’s relapse.
