Fear Street: Prom Queen takes place in 1988, before the events of Fear Street Part One: 1994, with references to the events of Fear Street Part Two: 1978.
The movie explores the Shadyside Curse, hinting at its origins and includes nods to previous Fear Street films, such as the Devil's Mark symbol and similar murder weapons.
Although Fear Street: Prom Queen has connections to the original trilogy, it mainly exists as a standalone film with minimal ties to the established lore and characters.
Director Matt Palmer's explanation for creating Prom Queen as a standalone film appears unclear, suggesting the decision was more for capitalizing on the Fear Street brand rather than expanding the existing storyline.
