While they stay in the town, completely isolated from the outside world, they are systematically separated and killed in gory fashion by the town's residents. Two students manage to escape, but upon alerting the authorities they learn that "Pleasant Valley" is nothing but a cemetery - a memorial for 2001 Confederate villagers who were massacred 140 years earlier by renegade Union troops during the Civil War. A plaque reveals that the town's residents will not rest until the crime has been paid back: 2001 villagers were killed, 2001 Northerners must be killed - an eye for an eye.
