A new promo has dropped for the season premiere, "Game On, Charles," and it seems Rosewood's most notorious killer is hell bent on psychologically torturing the Liars as they continue to fight their way out of his demented dollhouse.

"We are going to be punished for our actions for trying to escape from Charles and once we do escape, there are going to be some serious repercussions and scares, emotional as well as physical," actress Janel Parrish (Mona) explained to E! Online. "It's going to get dark."

The ABC Family drama will devote the first 10 episodes of the summer season to unmasking the infamous 'A'. Hanna, Emily, Spencer, and Aria uncovered their tormentors name in "Welcome to the Dollhouse," but Charles DiLaurentis face has yet to be revealed.

"The shotgun has gone off and we are racing to the finish line and it's just non-stop right now," series creator Marlene King explained to Us Magazine. "You know, I have often said we know who 'A' is but we take turns along the way so we don't get to the end of the road too quickly - well, the turns are over! So we're on the straight line to the end of the road."
