Taylor, once a troubled youth, persuades Cammi, an exemplary student, to accompany her and her friends on a Spring Break journey through the California desert. Despite Cammi’s ominous forebodings, the group of eight indulges in wild partying as they venture deeper into isolation along the historic Route 66, all while being pursued by a murderer. Tension escalates as each stop becomes increasingly bizarre, ultimately leading them to a deserted amusement park with a shadowy history, far from the main road. There, they encounter a park filled with dilapidated carnival rides, startling revelations, the scent of death, and a captivating, young, tattooed serial killer known as Spider.
