Dark Ride

Twenty years ago, twins were murdered inside a dark ride by a psycho who had taken up residence there. In the present day, the ride is due to be reopened. A group of teens in a van going to spring break find a brochure for the grand opening and decide to sneak in to see it. On the way, they stop to pick up a female hitchhiker who is pretty nutty in a seemingly harmless way.

The teens decide this would be a great place to spend the night as it will save money on a hotel room. They sneak into the dark ride and start exploring. (Technically it isn't a dark ride anymore since the track has been removed.) The group has fun until they realize they are not the only ones there and the door they came in is now locked from the outside.

In a bad stroke of luck, the killer has escaped the asylum that very night and is ready to continue his killing streak. What better victims than a group of kids who break into a place they shouldn't be?
