Hell's Highway is a 2002 horror film written and directed by Jeff Leroy.
Out on a highway in Death Valley, a man picks up a female hitchhiker named Lucindia, and gives her a drink. Lucindia has a coughing fit upon ingesting the liquid, stumbles out of the vehicle, and is stabbed to death by the motorist. The man (revealed to be a priest, whose offer to Lucindia was holy water) buries Lucindia's body, and erects a crucifix similar to the dozens dotting the roadside over the impromptu grave. As the preacher prays, Lucindia reappears and bludgeons him with his shovel as he shouts "El Diablo!"
