'During a camping trip to the Catskill Mountains, Charlotte's boyfriend Luke, a former soldier suffering PTSD, goes on a rampage, nearly killing Charlotte and her two friends. A year later Charlotte is a graduate student in the small college town of Ashenville, North Carolina. Yet her new life is shattered when Luke, recently released from prison, shows up on her doorstep, demanding to get back together. When it becomes clear to Luke that she is no longer interested in him, and she has in fact moved on with a new boyfriend, he vows to kill her. Now, it seems, Charlotte only has one option: Run.'
