Synopsis
Hanna comes up with a desperate plan to save her mother from a conviction and turns to the only person she thinks can help – Mona. Caleb tries to convince her Mona can’t be trusted, causing Mona to prove her loyalty in the most unexpected way. And Spencer returns to an old haunt to investigate new evidence relating to Wilden and his surprising ties to another mysterious death.

Meanwhile, “A’s” recent machinations take their toll on Emily and her mom, driving Emily to reconnect with her old boss Zoe to look for an escape. And Aria relies on Jake to help her understand Mike’s new attitude, leaving them both confused about the nature of their relationship.

Title and Background
The title seems to refer to being guilty and that the girl needs help on how to feel and what to do. It also may have to do with Mona being guilty about being on the A-team. Additionally, The Guilty Girl could be Alison and the Handbook her diary. Also, a released sneak peek, shows Mona training Hanna, to lie and plead guilty for Wilden's murder, so the title may refer to this process, a handbook to make yourself (In this case, Hanna) look guilty.
