The liars deal with the revelation that Alison is alive and wonder if she's been playing another game with them this whole time. Hanna shares her theory that another girl must have gone missing at the same time as Ali because a body was found under that gazebo and someone is in Alison's tomb. She finds a girl named Sarah Harvey who went missing Labor Day weekend, and Hanna and Emily meet up with Sarah's friends. Unfortunately, it seems like Sarah went missing the day after Labor Day, so she couldn't be the body. Meanwhile, Toby and Spencer get the company in charge of Radley to admit that Toby's mother didn't commit suicide ...and could possibly get the whole hospital shut down. And Ezra tries to win Aria back.
