They're Coming For Me

It's the beginning of October. Halloween decorations are already hung outside and being sold in stores. Halloween is Jade's favorite holiday and for the whole month she likes to watch the scariest movies. After coming home from the movie gallery, she turns the movie on and discover that someone recorded a warning over the movie warning her about the upcoming Halloween. The person warned that the next five people who watched the video would be able to see the suspicious events and are the only ones who can stop it. Being as wise as she is, she thought it was a hoax and returned it. After she does, four teenagers, one by one, also find the video and assume it's a hoax. Not too long after watching, they witness strange events that no one else can see. After realizing the video's warning is true, the teens meet up and plan how to stop the prevent the disaster before Halloween arrives.
