The film will take place entirely within a teenage girl's bedroom, where she is home alone. She begins to feel a presence and hear strange noises and shadows moving around the room. When she tries to escape through the door, she finds herself back in the same room facing the monster. The film will use camera techniques like low angles, close-ups, and color correction to build tension, as well as diegetic and non-diegetic sounds. It will feature a dark color palette and wide shots to create a sense of claustrophobia as the main character is trapped in the small space with the monster.
