Like most families, the Jensens gather together to celebrate the holidays. This year, since half the clan is scattered across the American West, they've decided to split the difference and meet up in Tucson. Matt and Luke will be there, for sure, and maybe Ace and Chance, too. That leaves Sally, Preacher, and Smoke Jensen, who've reserved three seats on a westbound stage to make sure they don't miss out on the festivities. What could possibly go wrong? Mother Nature is the first to strike, dusting up the trail with a sandstorm as blinding and deadly as any northern blizzard. Then comes an Apache ambush, forcing the passengers and drivers to seek shelter in a cave. Even if Smoke and Preacher manage to shoot their way out of this, they have another big surprise waiting, a ruthless gang of outlaws after the cargo of cash on the stage, happy to slaughter anyone who tries to stop them. If the Jensens hope to save Christmas this year, they'll need to save their own lives first.
