On her first day of college, Hailey was assigned to Hall 13, the most remote dorm on campus. Room 307 had a strange rule sheet: four residents per room, never acknowledge the "fifth person," lights out at 10 p.m., don't open the door after lights-out, use the bathroom on the right, and ignore strange noises. She thought it was a prank until a voice spoke to her through the stall, and a "fake Hailey" in a red dress appeared among her roommates. Worse, the rules each dorm received contradicted one another—following them led to blood, breaking them brought safety. Any outside call was cut off. Hailey allied with roommates Jasmine, Erin, and Laura. With help from the RA's mysterious white "candy," they discovered a hidden rule: break all rules to be "expelled." They chose to defy every rule one by one.
