Plot[]
Aria (Lucy Hale), Emily (Shay Mitchell), Hanna (Ashley Benson) and Spencer (Troian Bellisario) arrive at the Ravenswood Founders Day Celebration party, donning nineteenth-century attire. While at the party, Ezra (Ian Harding) calls Aria to check on her and advises her to be careful. He puts on his mask for his costume and enters the party. The girls spot Luke (Brett Dier) wearing a vintage soldier's costume similar to the one they found in Ezra's apartment. The girls split up to find Alison and examine Luke. Hanna spots two short blond figures in red coats while Emily is separated from Aria by Mrs. Grunwald (Meg Foster), who warns them to go away. Aria finds Leah (Elizabeth Whitson) in a ditch, pulls her out and learns that Luke is Olivia's cousin.
While on a bus to Ravenswood, Caleb (Tyler Blackburn) is approached by Miranda (Nicole Gale Anderson) after being frightened by the man (Irwin Keyes) she was sitting next to. Miranda tells Caleb about her past life and how she is going to Ravenswood to meet her uncle. Just as Caleb asks about her uncle, Miranda runs off to get some chips from the old man in the back of the bus. As she reaches into the bag, he awakens from sleep and she runs back to her seat. Caleb apologizes to Miranda about asking about her uncle and tells her his story about his uncle. Miranda tells him about her foster parent and decides to get off at the upcoming stop and go home. As she gets up to leave, she notices the man from the back of the bus and decides to stay.
As the girls, frightened and anxious, reconvene, they spot Red Coat and chase after her. They land in a mausoleum, but find that Red Coat has disappeared. The girls notice a spot in the mausoleum and discover a secret passageway. As they walk in, the door behind them closes without warning. The girls continue trekking through the passageway as gusts of wind begin hitting the girls. When the wind stops, Hanna has gone missing.
Hanna, while trying to find the girls, notices the phrase "HELP ME" written in red on the wall. As she turns on her cellphone light to read the message, she notices a swarm of rats on the ground and runs through a passageway, which leads to a door to a room in a mansion. Unbeknownst to her, a masked Ezra is lurking behind her. Hanna continues walking through the mansion until she finds a telephone booth. She tries to use the telephone, but it turns out to be a gag. Hanna tries to leave but finds herself locked in with three lights closing in on the outside. The lights suddenly disappear and the phone rings with a vintage record playing on the other end.
Caleb and Miranda arrive in Ravenswood and go their separate ways. Miranda walks into the mansion to explore. Meanwhile, Aria, Emily and Spencer find their way into the mansion and notice blood dripping from the ceiling. They suddenly hear Alison's voice and head off to find her, but Spencer gets separated from them. While trapped in the booth, Alison's face appears, but is dragged away and the masked man's image appears in its place. Miranda then frees Hanna from the booth and together they try to find a way out of the mansion. They enter a room filled with coffins, which triggers a painful memory for Miranda. As they leave, Miranda notices a booklet and takes it with her
Aria and Emily find a room with an open window and prepare to leave the house and get help. As they hear Alison's screams, the girls retreat and the window's jagged glass shuts behind them. Meanwhile, Spencer walks into a greenhouse where she discovers the masked man waiting for her. They wrestle before Spencer picks up hedge cutters. She slices the man's hand and knocks him out. She reaches for his mask, but he awakens and grabs her. She breaks free before hitting her head against a wooden ledge. He picks up the hedge cuts ad stands over her.
Caleb finds Miranda and Hanna while Aria and Emily find an unconscious Spencer. Hanna shows Caleb and Miranda the door to the passageway, but the door won't open. Meanwhile, Miranda finds a grave marker with her name and image on it. Aria, Emily and Spencer listen to Alison's cries for help and discover a tape recorder with her voice playing. Mrs. Grunwald enters the room and tells the girls that it is her room and the tape was stolen from her office. She later has a psychic feeling, warning "One of you has been touched by the one Alison fears the most." Hanna learns from the girls that Alison is gone.
Aria, Emily and Spencer find the car with a slashed tire. Miranda decides to go back into the house; Hanna sends Caleb off to help Miranda and returns to the girls, who have found the spare tire missing. Ezra pulls up and offers the girls a ride back to Rosewood. When they reach Rosewood, they discover Red Coat watching them and chase her into Spencer's backyard. Red Coat reveals herself as Alison and tells the girls she doesn't have time. She tells them that she wants to come back home but it still isn't safe. She runs away as Ezra approaches Aria with her phone. Back at Ravenswood, Miranda and Caleb discover a grave marker with Caleb's name and image on it.
