* CompleteMonster: Richard Fenton was a teacher who had hidden pedophilic urges towards his fourteen-year-old student, Donna, whom he began stalking and harassing. Once his obsession became exposed, causing him to get fired and be given a restraining order, Fenton decided he wanted Donna to himself, so he killed her family, including her [[WouldHurtAChild younger brother]], before being arrested. Three years later, Fenton breaks out of prison on Donna's prom night, and atteneds her prom party at a local hotel incognito, killing Donna's friends and anyone unfortunate enough to be in his way, including hotel staff. When bodies are found and Donna is taken home, Fenton sneaks into her house, [[SlashedThroat slitting her boyfriends throat]] while he is sleeping. He finally attempts to kill Donna as he is about to get gunned down by police.
* InferredHolocaust: Because [[NoEnding the movie ends right after Fenton dies]], we have no idea whether or not there would be heavy reprimands towards the police force for their incompetence or any consequences/fallout from the prom night ending in the murder of three teenagers.
* RootingForTheEmpire: When the police after the villain are as dumb as a pile of bricks, it's kind of hard not to root for him.
* TheWoobie: Donna, her pedophile teacher murders her family, and if that wasn't bad enough, when he breaks out, he manages to kill her friends [[spoiler: and boyfriend.]]
