An homage to exploitation B-movie thrillers that combines two feature-length segments into one double-bill designed to replicate the grind house theatergoing experience of the 70s and 80s. In "Death Proof," a psycho named Stuntman Mike (Kurt Russell) stalks and kills beautiful women with his car. In "Planet Terror," a small-town sheriffs' department has to deal with an outbreak of murderous, infected people called "sickos." A gun-legged woman named Cherry (Rose McGowan) and her martial arts-wielding partner (Freddy Rodriguez) take on the zombie army. The two films will be fused together by fake movie trailers.
