This tale is narrated in the first person by Booth, an elderly resident of a small town that neighbors Jerusalem's Lot, Maine. The main part of the story is set a couple of years after the events of 'Salem's Lot. Booth describes a winter's night years ago, when he and his friend, a bar owner named Herb "Tookey" Tooklander, attempted to rescue the family of a motorist named Gerard Lumley, whose vehicle had become stranded in a ferocious blizzard. At first mildly contemptuous of Lumley for driving in such weather, both men are horrified when they realize that Lumley's vehicle is stranded in Jerusalem's Lot. It is widely known that "the Lot" has gone bad, but they still decide to drive out in Tookey's Scout and attempt to save Lumley's family. Instead, they barely manage to save themselves from the man's wife and daughter, who have been turned into vampires, while Lumley himself ends up being vampirized by his wife. The story ends with Booth warning the reader that if they ever find themselves on the road through 'Salem's Lot, they should keep on driving and not stop for any reason.
This story acts as a sequel to 'Salem's Lot, and is also connected to the story of "Jerusalem's Lot" which is a prequel to both, and also appears in Night Shift. Both stories were later collected in the 2005 'Salem's Lot Illustrated Edition.
