This slice-n-dicer marks Denmark's first foray into the teenage-slasher movie genre. This one is different in that it contains a sci-fi element in lieu of a supernatural one. It all ends and begins (simultaneously it turns out) at Elf Hill High School as seven young people are called to detention in the biology lab. They are locked in and forced to watch a television screen that informs them that somewhere in the school a murder has occurred. One fellow then climbs out a window to investigate. Later it is discovered that he killed his own brother. The door then opens and two girls flee. They are separated and one of them is found dead. Soon the kids are dropping like flies. Suddenly the story moves outside the high school where a correspondent for the TV reality show "Final Hour", which covers murders and other atrocities while they are happening, is seen narrating the events. For some reason this reporter seems to know what will happen before it happens.
