When a group of six college friends (led by Jamie-Lynn Sigler) set off on a Spring Break road trip, they look forward to a weekend of drinking, dope smoking and partying. Meanwhile in a nearby mental institution, the notorious Carnival Killer - convicted of slaughtering twin girls in a fairground ride ten years before - brutally butchers his two guards and heads back to his Dark Ride ghost train. When the kids stop for gas at a highway service station, a terrifying chain of events is set into motion that will inevitable lead them to the demonic killer. Soon their fun becomes a blood-soaked nightmare and a battle to survive until morning amidst the several heads, spinning tunnels, witches lairs and haunted crypts that fill the Dark Ride. For many of the college kids this will be the last ride they ever take!
