When his latest assignment takes him to the set of a low-budget horror film, he's overjoyed to learn he'll be driving Riversa Red, his favorite B-movie Scream Queen. While driving his beloved idol, Don assumes the role of bodyguard and turns angrily protective, especially after learning that Riversa has a stalker. Hell-bent on protecting his queen and fueled by paranoid fantasies, Don's usual temper tantrums go to deadly extremes. Soon he proves to be not only Riversa's biggest fan, but also her worst nightmare.
