Framed for murder, Dewey "Mac" McKenzie is running for his life. Though Mac's never even made a pot of coffee, he talks his way onto a cattle drive heading west, as a chuckwagon cook. Turns out he has a natural talent for turning salt pork and dried beans into culinary gold. He's as good with a pot and pan as he is with a gun, which comes in handy on a dangerous trail drive beset with rustlers, hostile Indians, ornery weather, and deadly stampedes. Mac can hold his own with any cowboy twice his age. At least until the real showdown begins.
