The girls are in for a rough ride when they return to Rosewood in the winter premiere of the hit series "Pretty Little Liars" season 6.

Spoiler TV reports that episode 11 titled "Of Late I Think of Rosewood" will see Hanna Marin (Ashley Benson), Emily Fields (Shay Mitchell), Spencer Hastings (Troian Bellisario), and Aria Montgomery (Lucy Hale) reunited after being apart for five years. The incident with "A" is obviously past them, as they have been living their life the way they want it to be, away from the shadow of their hometown.

The Liars will not be able to say no to Allison's (Sasha Pieterse) request for a reunion, though, as all of them decide that the time is right to come home, after all. Unfortunately, they will not be ready for a new wave of lies, deceit, and terror that are about to befall them once they arrive. A more dangerous foe is waiting for them, anticipating the moment wherein they will be at his/her mercy.

According to Hollywood Life, the girls should be terrified of this new villain, as he/she is miles different from Cece Drake (Vanessa Ray) aka "A." While the person who tormented the Liars for a longest time is into playing tricks, the new antagonist likes to kill. He/she will reportedly go on a killing spree and terrorize the residents of Rosewood.

Even though they have weathered a lot in the past, the girls are in for a different experience, as they will even find themselves doubting one another. Past secrets will be revealed, while new lies will emerge. Before they know it, the best friends have turned on each other, as suspicions prevail among them.

"Pretty Little Liars" season 6 winter premiere will air on Tuesday, Jan. 12, 2016, at 8 p.m. EST on Freeform (formerly ABC Family.)
