Pretty Little Liars' new big bad will up their game in "Burn This."

'Pretty Little Lairs' Season 6: Get Ready For A Wedding! Who Will Tie The Knot In Episode 7?

So far, post-college life in Rosewood has consisted of very few attacks (Charlotte's murder being the one major exception), but the Liars will find themselves running for their lives once more in episode 8.

Since her life wasn't already hard enough, the attacker will put Emily (Shay Mitchell) in the cross hairs first.

"After the stalker nearly killed Emily, the Liars begin to take the threats more seriously and attempt to keep their mouths shut to prevent any further harm," Freeform announced. Emily, however, will "go on a mission to track down who came after her."

Despite Ms. Field's peril, the other liars will have their own problems to deal with. While Hanna (Ashley Benson) avoids dealing with her personal life, Aria (Lucy Hale) and Ezra (Ian Harding) will move on with his their novel and Spencer (Troian Bellisario) will attempt to comfort Caleb (Tyler Blackburn) after he takes the blame for a problem with Yvonne.

"Burn This" will air March 1. In the meantime, viewers can catch "Do Not Disturb" (Feb. 9) and "Where Somebody Waits For Me" (Feb. 16), "We've All Got Baggage" (Feb. 23).

Pretty Little Liars airs Tuesdays at 8 p.m. ET on Freeform.
