After dying with her three roommates in a mysterious dorm-room attack, college senior Chloe Whitfield wakes up twenty minutes before the same nightmare begins. At 11:40 p.m., strangers pretending to conduct an emergency headcount knock on Suite 407. This time, Chloe refuses to open the door. Her roommates think she is paranoid, but the callers know their names, disciplinary records, and even possess a master key. As fear turns into a desperate fight for survival, the four women barricade the room, call 911, and uncover a disturbing truth: someone inside the university has been selling students’ private housing information to outsiders. With police closing in and trust inside 407 pushed to the breaking point, Chloe must use everything she remembers from her first life to keep them alive. One wrong decision could repeat the tragedy—but this time, Suite 407 is determined to survive until sunrise and expose those responsible forever.
