Pretty Little Liars Promo: Season 4, Episode 8: “The Guilty Girl’s Handbook” (VIDEO)

How far will Hanna go to save her mom? This thrilling preview of Pretty Little Liars Season 4, Episode 8: "The Guilty Girl's Handbook" (July 30) gives us a clue.

This promo begins by focusing on the aftermath of the crash ("'A' really likes throwing cars at people" Spencer says, which is hilariously true), before switching to put the spotlight on Hanna's desperation.

"Hanna would do anything for you," Caleb tells Ashley Marin. "That's what I'm afraid of," Ashley responds. This mama knows her daughter, and like any good parent, she cares more about her daughter's safety than her own. That doesn't stop Hanna from apparently turning to Mona for help, however. Yeah, there's no way that could go wrong...

And which Liar "pays the ultimate price"? This promo has us worried!

For more info, check out the official synopsis of the episode:

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 (Rumer Willis) to look for an escape. 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.
