The maniacs decided to make a slasher series where there isn't a killer. And at least for this entry, it works.

Wendy is a precog who gets a vision of herself and her friends dying horribly on a rollercoaster. She stops her friends from riding, and death gets angry. And when death gets angry, he makes ample use of one small town's horrendous safety standards to off those kids... horrendously.
