Aria, Emily and Hanna keep looking for a way to prove Ali's innocence without incriminating Mike (recurring guest star Cody Allen Christian). But when the District Attorney proposes a plea bargain agreement for Ali that includes naming one of the PLLs as her accomplice, the girls intensify their search — not only to save Ali, but to save themselves. Will Ali stick by her story of innocence or will she give up one of the PLLs to save her own skin? Meanwhile, not knowing what is happening back in Rosewood, Spencer gets a much-needed break from all the drama with a night out on the town in London.

Equipped with their new information about Mona, the Liars decide they need to speak to Alison. But once the truth is out there, Aria quickly learns that Mike's (recurring guest star Cody Allen Christian) involvement with Mona and this new revelation could have serious repercussions for her family. Determined to keep Mike safe and get Ali out of jail, the Liars intensify their search for information on "A." Meanwhile, Spencer heads to London for an important college interview, and Alison looks to someone surprising for help with her murder trial.
