In addition to explaining the origins of the film, the article tells the following about the plot:
The Paramount Pictures release is set in Ohio in 1979 and introduces a troupe of six youngsters who are using a Super 8 camera to make their own zombie movie. One fateful night, their project takes them to a lonely stretch of rural railroad tracks and, as the camera rolls, calamity strikes — a truck collides with an oncoming locomotive and a hellacious derailment fills the night with screaming metal and raining fire. Then something emerges from the wreckage, something decidedly inhuman.
