No abras la puerta al anochecer

First night at Blackwood University's old dorm, power cuts early. Ethan and three roommates trapped in Room 308 — a broadcast plays eerie campus rules. Punishment for violation unknown. Screams outside, monsters at the window. They survive by silence. Dawn comes. Last night's victims reappear twisted. The cafeteria's brisket hides a mind-trapping trap. Rules blur truth and lies — the campus hides a monster food chain. And one minute is always missing. As danger closes in, Ethan decodes the broadcast's clue and moves the clock. Morning returns, horror like a dream. But the traces left behind prove — the terror isn't over.
