Moments after where the season four finale left off, Aria and the Liars are reeling from Ezra’s shooting at the hands of “A.” The five girls quickly realize that as the one person who truly knows A’s identity, Ezra is in grave danger. While Aria stands watch over Ezra at the hospital, Alison and the PLLs lay a trap to finally flush out “A” but are shocked by who is ensnared. Meanwhile, Holbrook steps up his efforts to find the girls and puts the Hastings family on alert. And as news of Alison’s resurrection spreads, Mona is not pleased. It is a rough time for all of the Liars as Spencer is reeling about the memories from her “lost summer,” Aria is still nursing a broken heart, Emily is reeling from Paige’s betrayal and Hanna unsuccessfully attempts to wade back into the dating pool. But as each girl tries to deal with her individual issues, they must focus their attention on their suspicions surrounding Mrs. DiLaurentis. Assuming that Mrs. D knows more about Ali and the night she went missing, girls decide to help out at her charity bridal fashion show to gain access to the DiLaurentis house to search for answers. Meanwhile, Ella and Jason return to Rosewood, each with something to hide. Emily takes up the sleuthing reins as she searches for answers about Ezra and Mona.

Tanner with a possible new lead in Alison's case. Meanwhile, Spencer and Aria lean on new men in their lives to recover. Emily, Hanna and Spencer are concerned for Aria as they watch their friend crumble after learning shocking news about Ezra. Not knowing what is true or what to trust, Aria goes looking for answers, not wanting to believe this revelation to be true. While concerned for Aria, Spencer is not doing so well herself. Trying to prove to her parents and Toby that she can kick the habit on her own, Spencer has to be careful because one misstep could send her to rehab. But can Spencer really rein it in, or will her constant curiosity and drive be her undoing?
