The Focusing Effect.

For his final project for film class in college, Kevin Morris, with the help of his girlfriend Julie and his roommate Jay, is making a documentary in which ex-couple share their breakup stories individually. When he comes across a disturbing secret involving one of his subjects (Ashley), he goes against his better judgment and shares it with Ashley's ex-boyfriend, James. But when the results are anything but satisfying, things start to get dangerous as James acts more ominous and it seems the lives of Kevin, Julie, Jay, and Ashley are soon in question.
