Blackbridge State Hospital feels half-mapped and half-dreamed, a subterranean wing under a bell tower where badges die, cameras blink snow, and an elevator opens to nowhere the blueprints admit. The atmosphere is palpable, but the rules of the place — why the key matters, what the crescents signal, how the ward seals — stay so slippery that the stakes soften instead of sharpening.
Graduate nurse Lena Morrow is spending the graveyard shift on Blackbridge State Hospital's sealed Eclipse Ward, a lightless wing beneath the bell tower in Lakeport, Michigan. She has dreaded this rotation since the incident in Room 614, a secret she hid with a forged chart and a broken wristwatch. As the hours drag and the generator stutters, the intercom coughs with voices that do not match the census, elevator C opens to a corridor the floor plan omits, and the med-room clock keeps resetting to 10:10.
When the security tech in the glass booth stops answering and call lights bloom over empty beds, Lena understands patients and staff are vanishing. The only clue is surgical tape folded into crescents and a brass key stamped QUINE, the disgraced founder. As doors lock and badges fail, it becomes clear everyone inside Eclipse Ward is in grave danger. Lena's worst fear was returning to the East Annex for one night. Now the siren outside wails for a town that cannot hear them, and she might never reach the last set of steel doors.
