A young girl gets a graveyard shift at a gas station situated in the middle of nowhere. She tells her boss that she has done time in prison for burning her serial killer boyfriend who survived the burns but is now incarcerated. However she doesn't mention to the boss or her parole officer about the paranoid delusions that she recently has started suffering from. Things go from weird to downright complicated on the very first night on the graveyard shift as the line between reality and illusions blur.
