After writing a sexually explicit essay, college freshman Jade is referred to the university's free counseling program where she learns her sessions will be observed and taped for training purposes. Behind the two-way mirror are Sam, a first year grad student, and Marty, an undergrad film student who runs the observation room's decrepit AV equipment. Both quickly begin observing Jade's sessions with more than just a professional interest. What follows is a spiral of obsession and betrayal that blurs the lines between reality and fantasy.
