Hanna (Ashley Benson) and Caleb (Tyler Blackburn) work together to develop a plan to come face-to-face with the tormentor in “Did You Miss Me?,” in an all-new episode of Pretty Little Liars, airing tonight at 8 p.m. ET/PT on Freeform.

After Alison (Sasha Pieterse) is confronted with a sudden, mysterious jeopardy, the Liars decide to take things into their own hands for a counterattack. Meanwhile, Emily (Shay Mitchell,) and Spencer (Troian Bellisario) team up to investigate if Mona (Janel Parrish) had any involvement with the murder. Aria (Lucy Hale) and Ezra (Ian Harding) continue to work on the book though it might be more difficult than anticipated.
