An intriguing riddle from -A has the Liars hitting the road and heading to Ravenswood, where they are surrounded by some familiar faces. During a very special magic show, one Liar pulls a disappearing act, leaving the other three scrambling to make sure she hasn’t succumbed to -A’s tricks.
But before they can hightail it out of Ravenswood, they make a shocking discovery that proves that everything they thought they knew about -A and the -A team might be wrong. With this discovery, the Liars may just have started ‘World War A.’
Meanwhile, Hanna and her mother’s joyous reunion is cut short when -A’s sights are set on a new target. And Toby uncovers some surprising information about Wren.

Hanna comes up with a desperate plan to save her mother from a conviction and turns to the only person she thinks can help – Mona. Caleb tries to convince her Mona can't be trusted, causing Mona to prove her loyalty in the most unexpected way. And Spencer returns to an old haunt to investigate new evidence relating to Wilden and his surprising ties to another mysterious death. Meanwhile, -A's recent machinations take their toll on Emily and her mom, driving Emily to reconnect with her old boss Zoe (a charity organizer who previously worked with Emily) to look for an escape. And Aria relies on Jake to help her understand Mike's new attitude, leaving them both confused about the nature of their relationship.

Spencer and Emily make plans to visit a nearby college, but they have very different agendas for their time spent on campus. Spencer's singular focus in figuring out Ali's apparent connection to the school contradicts Emily's real fears about her plans for after she graduates. And after a stinging attack by "A," Aria and her brother Mike don't see eye to eye regarding what's best for their parents.
Meanwhile, Hanna becomes increasingly frantic when she makes another horrifying discovery among her mom's things, leading her to make a desperate move - with disastrous results.
