Plot
College students Anderson, Nelson, and Cory become lost while heading to Daytona Beach for spring break, and follow a 'Detour' sign that leads them to the southern town of Pleasant Valley, led by eccentric mayor Buckman. Three other travelers - Ricky, Kat, and Joey - arrive shortly afterwards, and Buckman tells them that for the next two days they will be honored guests at the town's annual 'Guts N Glory Jubilee.' They are joined by two other travelers, interracial biker couple Malcolm and Leah, and all are given rooms at an inn run by Granny Boone and her son Hucklebilly.
Soon after settling in, Kat is killed by being drawn and quartered, her body being served as a dish for the others. Later in the evening, Nelson is killed when he drinks battery acid, thinking it's moonshine. The following day, the group are separated and go off into different areas of the town.
Leah is dressed in a southern dress and motioned to come up to the podium during a celebration, where Granny Boone pulls a rope and crushes her with a large bell. Ricky sees this and runs off to alert the others, but he is accosted by Buckman's son and held down as two female residents impale him with a large poker.
Joey finds Kat's dog tags and the group realizes that both Kat and Nelson have been gone for a long time. They make a plan to find their missing friends and belongings, and then get out of town, but are stopped by Buckman making subtle threats.
Malcolm sets off to find Leah and is lured to a cotton press, where he is killed after being crushed. Cory and Joey head to the hotel to get their belongings, but Cory forgets his phone and leaves Joey to go get it. Joey finds a cabinet filled with jars of different body parts and dates reflecting many years of Jubilees, but before she can run off, she is captured. Cory returns to his room and is seduced by one of the townsfolk. He sits down, thinking that she is going to perform oral sex, but instead she puts on metal fangs and mauls his crotch, killing him.
Anderson finds Malcolm's motorbike being guarded by Hucklebilly in the barn, and although he attempts to goad him into giving him the keys, Hucklebilly knocks him out. Later that night, Anderson and Joey find themselves tied up by the townsfolk, who taunt them for coming into their town. Buckman shows the two their friend's severed heads and tells them that their bodies are the barbecue the townsfolk will feast upon. Buckman offers to spare Anderson if he kills Joey, since he was originally from the South, but he refuses. Anderson and Buckman have a battle that ends with Anderson ripping Buckman's eyepatch off, revealing it to be an empty hole with maggots inside. Buckman pleads with Anderson not to take his other eye and lets him and Joey go.
The next day, Anderson and Joey go to the local authorities, who are skeptical, but follow them to Pleasant Valley. When they get there, the town has disappeared and is nothing more than a graveyard. Anderson reads a plaque that reveals that during the Civil War, a group of union troops came and massacred everybody in the town, now the residents will not rest until they avenge their deaths, revealing that the residents that the group met were the vengeful ghosts of the townsfolk.
As the two drive away on their motorcycle, they are decapitated by barbed wire, which was placed by Hucklebilly. He picks up their heads and vanishes as he walks down the road.
