While Spencer (Troian Bellisario) is still in London for a college interview, Aria (Lucy Hale), Emily (Shay Mitchells), and Hanna (Ashley Benson) are busy in Rosewood to prove that Mike (Christian Cody) and Ali (Sasha Pieterse) have nothing to do with Mona's (Janel Parrish) death. But can they all do this without putting one of them in jail? 

In the promo trailer for episode 22 titled "To Plea or Not to Plea," Caleb (Tyler Blackburn) tells Hanna that her warrant of arrest has been ordered by the judge. But he will not let her go behind bars for something that she never did, which is why he persuades her to tell the entire truth. However, she believes that "A" will still go after them no matter what. 

Also, the trailer shows a frightened Ali, who seems to be running away from someone while still in prison. Did "A" manage to sneak past the police to torment Ali once again? 

But aside from their "A" problems, Aria might also have to face a little love problem of her own after she kissed Andrew (Brandon W. Jones) in episode 21 dubbed as "Bloody Hell." In a sneak peek for the upcoming episode, Emily finds a note from Andrew in Aria's locker asking her out to dinner. Emily confronts her about it, and Aria admits that she and Andrew kissed during one of their study sessions although it was just a spur of the moment. 

Emily asks Aria about Ezra (Ian Harding), but Aria says that she has no idea what is going on between her and Mr. Fitz at the moment. It seems that Aria is preoccupied with Mike and Ali's case, which is why she does not want to think about her current relationships anymore. 

But can the Liars find a way to help save themselves from "A's" evil schemes?

"Pretty Little Liars" season 5 episode 22 airs March 3.
