Plot

Spencer's numerous sleepless nights, with the help of prescription pills, take a toll on her as her hunt for Ali and much needed answers continues, teleporting her into the world of 1940s film noir.

We open with Spencer, Hanna and Emily in Ezra's classroom looking for some kind of evidence they can use to prove to Aria who he really is. They find Alison's journal in one of his desk drawers. While they hide in the hallway they spot Mona walk into Ezra's classroom. She comes out with a stack of papers.

Back at Spencer's place the girls look through the journal. They want Emily to ask Paige about Shauna. Emily wonders if perhaps they found the journal too easily.

Aria and Ezra are together in the car. She tells him about a story she's working on and they talk about heroes and villains.

With her parents out of town Spencer sits at home watching old movies. Suddenly the scene morphs into a back-and-white scene, complete with time-appropriate décor. Toby walks in wearing a trench coat looking like an old timey detective. (The whole episode will be this way, it seems.) Tobey asks her about the drugs she's taking

Ezra approaches Spencer at the coffee shop. He asks her about returning to that bar where she found him the other day and she lies about having returned.

The girls talk about the likelihood that Aria is probably still with Ezra and lying about it. Hanna is put in charge of watching Ezra. Aria arrives and the girls ask about her trip.

Spencer calls a number and reaches the Fitzgerald Art Foundation. She hangs up without leaving a message. Toby confronts Spencer again about her pills. They talk about a painting of Alison on the wall and the possibility she's is alive.

Hanna watches Ezra and Mona on the balcony outside his apartment. She hands him a drink and they go inside.

Emily asks Paige about Shauna. She says she told her everything.

Hanna runs into Mona on the street.

Mona calls Spencer and tells her there's a "blonde package waiting for you" at Ezra's apartment. Spencer rushes there and Ezra confronts them about tailing him. He says he's back with Aria, to which Spencer warns him to stay away. He thinks they haven't told Aria about him because they aren't sure and tells Spencer she's in over her head.

In the car Spencer tells Hanna the number from Alison's journal led her to the art foundation.

Paige tells Aria about going on a canoe trip with Emily.

Ezra has a drink with Toby. He tells Toby that Alison is alive and that Spencer knows how to find her.

Alison shows up at Spencer's place. She's upset Alison didn't tell them about Ezra or warn Aria. Alison mentions Spencer's pills. Toby shows up but Alison has left.

Toby sits Spencer down and asks whether Alison is alive or dead. He wonders if perhaps Spencer was helping Alison.

Aria tells Ezra she wants to tell her friends about their relationship. He tells her that Alison is alive.

Hanna learns what answering service the Fitzgerald Art Foundation uses for evening calls.

Emily promises Paige she won't let her be alone. They're both scared about being found out. They fool around.

Hanna calls the Foundation's service looking for a message from an "Alison."

Spencer tells Toby she's not sure who A really is. Toby tells her she knows the next step to find Alison. He thinks it's no accident that she has Alison's book.

Aria tells Spencer she's seeing Ezra again. She says she loves him, but seems conflicted about how things are going. Spencer is about to tell her about Ezra but Hanna interrupts to say she's found Alison.

The girls go the place where the message from Alison originated and find her. She tells them to "get the hell out" and rips into Spencer for bossing everybody around. Spencer responds by charging her with trying to set them up. Alison asks Aria "has she told you?" just before a bullet comes through the window. Everybody scatters. Downstairs they hear Ezra's voice. He says "I don't know what they told you but it's not true." Nobody will tell Aria what is going on and she goes to him. When she gets there it is Toby, who says he knocked out Ezra. They get in a car and speed off.

In the car Aria asks Spence why Toby hit Ezra. Nobody has the courage to say anything. Toby asks Spencer about the Alison's book and they argue. He tells her to look at the pages themselves.

At this point Spencer snaps back into "real life" and goes over to Alison's book. She goes to Emily and Hanna and tell them it's a Trojan horse. There have been changes made to the journal from the pictures she took. A doesn't realize they have the original pages on Spencer's phone, which means the girls have the upper hand once again.

The girls go to Aria's place. The episode ends with them looking through the window and seeing Ezra and Aria kissing.
