Sinopsis

Jesse, a young college student, has insisted to his best friend, Stella, that he is being stalked. No one believes him and thinks he has gone off the rails because it’s almost exam week. Stella convinces him to attend several parties for the "college experience" and to see the man Jesse is "obsessed" with. During these parties, Jesse gets a taste of Hayden’s attention. Once Jesse gets what he wants, things take a turn for the worse. Was he being stalked the entire time? Or was he imagining things?
