The story concerns an abandoned red Cresswell truck owned by Otto Schenck and George McCutcheon, wealthy
Castle Rock businessmen in the post-depression era. After Schenck deliberately crushes McCutcheon beneath his derelict vehicle, the murderer becomes fixated on the truck. Schenck insists that the truck is not only moving on its own accord, but planning to kill him. At the same time, he becomes a social recluse, living in a house he built across from the truck itself, and generally begins to lose his sanity. Schenck's nephew, who tells the story, finally finds him dead – the corpse has been drowned with
motor oil and there is a
spark plug rammed down his throat. The nephew goes on to describe how, on the day he found his uncle dead, he began to see strange happenings with the truck himself. Also, he couldn't accept his uncle's death as a suicide because there was no jug near the body with which Otto could have fed himself the oil. The nephew would dismiss what he saw as a hallucination, were it not for the derelict spark plug he took away from the corpse and kept as a reminder. ==Adaptations==
