But when a creepy Halloween party invitation leads her and her new group of friends into the middle of a terrifying mystery, their lives spiral into a nightmare they can't escape. After a brutal murder and a bloodstained note inviting them to a deadly "scavenger hunt," Kayla, Hardin, Ivy, Jenny, Miles, Scarlett, Brandon, Sarah, and David are forced into a twisted game inside an abandoned mansion tied to a killer from the past. Each clue drags them deeper into fear, secrets, and horrifying rooms built from their worst nightmares. As friendships crack, romances ignite, and trust begins to disappear, the group realizes this isn't just a game. Someone wants them terrified... and maybe even dead. Now Kayla must uncover who's behind the scavenger hunt before the night turns into a massacre none of them survive. Because once the game begins... There's no way out.
