Currently serving time on house arrest, disgraced music star Reese is surprised to learn that he still has a fan in the form of delivery driver, Eva. The two form an unlikely friendship that begins to sour due to Eva's growing obsession and her struggles with PTSD, stemming from hardships suffered during her service in the army. As Eva's psychotic break continues to grow, Reese finds himself locked down literally from his criminal sentence and figuratively by the fear of his biggest fan's unpredictable behavior.
