Scene opens on a beautiful summer day as 18-year-old Kacey drives over to her friend Andi’s house. A backpack, board games, and pillow are tossed in the back seat and the radio is on. Kacey and Andi have been best friends since childhood and are practically inseparable … even after Kacey’s family moved out of town. Now, it’s the final weekend before both girls move out of state to attend different colleges so Andi has invited Kacey over for a ‘girls’ night’ sleepover … for old times sake. When Kacey arrives at the door, Andi greets her enthusiastically. The BFFs giggle and hug before grabbing Kacey’s things and heading inside. Andi seems slightly unhinged, looking over her shoulder as she closes the door. The girls settle into the living room and start to catch up when their conversation is cut short by Andi’s step-brother Todd returning home. Kacey has always been very wary about Todd. He was the black sheep of Andi’s family, unemployed, in and out of trouble, and very aggressive. He had moved back in this Summer after a stint in the army and Andi had been very quiet about it. Now, the moment the brother walked in the room, Andi’s behavior changed dramatically … from outspoken and giddy to nervous and reserved. Kacey notices this but, before she can react, Todd slides on to the couch and crashes their conversation. Throughout the dialogue, he keeps putting his sister down in front of Kacey and making lewd jokes at her expense, while being very touchy and flirtatious at the same time. Andi takes it without a word, staring blankly at her best friend. This is not a normal way for siblings to treat each other and the situation makes Kacey feel very uncomfortable, especially when she catches Todd leering at her too. Later that night, after an evening of board games and makeovers, Kacey and Andi undress to get ready for bed. As the girls strip out of their clothes, Kacey notices some strange markings around one of Andi’s wrists. When she asks about it, Andi shrugs it off and quickly changes the subject. An awkwardness hangs in the air around them until Kacey breaks the silence by asking to use the shower. Her best friend seems relieved and grabs her a towel. As Kacey rinses off, she can’t help but feel uneasy. She leans up against the wall and scrubs herself, lost in thought. You can tell she’s thinking about Andi. She turns the shower off and pulls the curtain back in time to see Todd darting out. He had clearly been in there watching her. Kacey quickly grabs her towel and wraps it around herself. Back in Andi’s room, Kacey tries to explain what happened but Andi is quick to dismiss her, making up excuses about how he must have accidentally walked in. She tells her BFF that she’s tired and the two girls turn out the lights. In the middle of the night, Kacey wakes up to strange noises. Slowly rolling over, she realizes that Andiand Todd are having sex aggressively on the bed beside her.
