Welcome to Y4, the secret ICU where the supernatural comes to heal. Edie is the newest hire on the night shift, a human nurse tasked with managing "non-normal" patients who can thrash through six-point restraints while under enough sedation to kill a horse. Locked away in the basement of County Hospital, Edie must balance her medical ethics against the terrifying reality of her patients' chipped fangs and superhuman strength. She’s here to pay off a debt, but the cost of working at the intersection of medicine and monsters is higher than she ever imagined.---A SIGNAL BOX STUDIO PRODUCTION📝 Written by Cassie Alexander🧠 Showrunner: Ainsley Bay⚡ Production: The Signal Box---System Note:This human-designed series includes AI and other software tools in its production via our proprietary Signal Box platform.Signal Box: Fiction’s Next Chapter.-----Want to binge Nightshifted with fewer ads?
