This document provides details for a psychological horror film trailer called "Detritus" that is targeted towards teenagers aged 15-25. It draws inspiration from the film "Paranormal Activity" and explores themes of peer pressure and society's punishment of rebellious teenage behavior. The trailer will follow the typical horror structure of introducing characters, building tension as occult markings are discovered in an abandoned house, possessions and killings occurring one by one, and the "final girl" escaping due to her purity. White contact lenses will be used to emphasize demonic possession and the characters follow common horror archetypes based on Vladimir Propp and Tzetvan Todorov's theories.
