William Loeb is a successful serial killer traveling the country, always tormenting his brother, Samuel, in a vain attempt to force him to join his killing spree. After losing everything to his psychotic whims, Samuel decides to face him, finally. Robin, a waitress at a 24-hour diner, falls for William, just another customer coming off the road, but this one choice will change her life forever. All three will face their destines in the booth of a 24-hour diner off the interstate, where anyone giving notice would just shrug their shoulders, declaring this is just ANOTHER NIGHT.
