The Classroom It’s the first day of the new school year at Blackwood High, an old, ivy-covered building with a dark reputation. A group of five students—Emma, the curious overachiever; Jake, the class clown; Mia, the skeptic; Ryan, the quiet artist; and Lila, the new girl with a mysterious past—are assigned to clean out the abandoned Room 13 as part of a detention punishment. The room has been locked for decades, and rumors swirl about its connection to a tragic incident involving a group of students who dabbled in black magic. As they enter the room, they find it frozen in time: dusty desks, faded chalkboards, and an eerie symbol drawn in red on the floor. Lila, who seems to know more than she lets on, warns them not to touch anything. But Jake, ever the prankster, picks up an old, leather-bound book from the teacher’s desk and jokingly reads aloud a Latin incantation written inside. Suddenly, the room grows cold, the lights flicker, and the symbol on the floor begins to glow. The students hear a faint whisper, but when they turn, no one is there. They laugh it off, but as they leave the room, they notice a strange mark on each of their hands—a small, black crescent moon. Over the next few days, strange things begin to happen. Emma starts having vivid nightmares of a shadowy figure standing at the foot of her bed. Jake’s pranks turn darker and more dangerous, as if he’s no longer in control of his actions. Mia, the skeptic, begins seeing fleeting glimpses of a girl in an old-fashioned school uniform staring at her from the corners of the school hallways. Ryan’s sketches become increasingly disturbing, filled with images of the symbol from Room 13 and a faceless figure. Lila, meanwhile, grows more withdrawn, as if she’s hiding a terrible secret. The group decides to investigate the history of Room 13. They discover that fifty years ago, a group of students performed a black magic ritual in the room to summon a spirit for revenge. The ritual went wrong, and the students vanished without a trace. The only clue left behind was the same symbol now marked on their hands. The students realize they’ve been cursed by the spirit summoned in the ritual. The mark on their hands is spreading, and they begin to experience terrifying hallucinations. Emma is haunted by whispers in the library, Jake is nearly pushed down the stairs by an unseen force, and Mia finds herself locked in the school basement with no way out. Ryan’s sketches start coming to life, and Lila reveals that her grandmother was one of the students who vanished—and that the spirit is using them to finish what it started. Desperate, the group decides to perform a counter-ritual to break the curse. They return to Room 13 at midnight, armed with candles, salt, and the old book. But as they begin the ritual, the spirit manifests—a twisted, shadowy figure with glowing red eyes. It taunts them, revealing that it feeds on fear and will only release them if they sacrifice one of their own. The students argue over what to do. Jake, consumed by the curse, tries to attack Emma, but Ryan intervenes. Lila, who has been hiding a book of protective spells from her grandmother, suggests an alternative: they can trap the spirit in the book by offering it a piece of their souls instead of a full sacrifice. But the process is dangerous and could leave them permanently scarred. As the spirit grows stronger, the students perform the spell. One by one, they recite the incantation and cut their palms, letting their blood drip onto the book. The spirit screams in rage as it’s pulled into the pages, but not before it delivers a final warning: "The curse is never truly broken." The students survive, but the marks on their hands remain, faint but still visible. They return to their normal lives, but strange things continue to happen. Emma sees the shadowy figure in her dreams, Jake’s pranks still have a dark edge, and Mia swears she hears whispers in the hallways. Lila disappears shortly after, leaving behind only a note: "It’s not over." The final scene shows the book, now locked in the school’s archives, glowing faintly as a hand reaches out to open it.
