Caleb and Ashley share the same fear that Hanna won't stop at nothing until her mother gets released in the next episode of "Pretty Little Liars". In her desperate attempt to save her mother from a conviction, Hanna turns to the only person she thinks can help, Mona.

Caleb tries to convince Hanna that Mona can't be trusted, causing Mona to prove her loyalty in the most unexpected way. But Hanna may have to pay the prize for her mother's freedom, being convinced by Mona to "tell the truth" and is later seen pulling a gun in a preview for the upcoming outing.

Meanwhile, "A's" recent machinations take their toll on Emily and her mom, driving Emily to reconnect with her old boss Zoe (Rumer Willis) to look for an escape. Spencer returns to an old haunt to investigate new evidence relating to Wilden and his surprising ties to another mysterious death, and Aria relies on Jake (Ryan Guzman) to help her understand Mike's new attitude, leaving them both confused about the nature of their relationship.

"The Guilty Girl's Handbook" will air Tuesday, July 30 at 8/7c on ABC Family. Pictures of the episode have landed online, giving a first look at Rumer Willis' guest-starring appearance.
