A new "A" player is in town and is determined to show the Liars that he/she means business. After getting a gruesome reminder that "A" is still calling the shots, Aria, Emily, Hanna and Spencer try to quickly devise a plan on how to deal with this old/new threat and the usual game that has been taken up a notch. Spencer and Hanna continue to play with fire as they look for answers, while one of Aria’s past indiscretions becomes fodder for "A’s" game. Meanwhile, a still very shaky Emily tries to focus on school but could easily be derailed when she remembers a crucial piece from "that night."
