Framed for a murder he didn't commit, Dewey "Mac" Mckenzie is a wanted man who ends up on a cattle drive heading west, learning on the job to be a chuckwagon cook. He's got bounty hunters on his tail, no one on his side, and no place to hide. Just when he thinks it can't get any worse, he hears the rumbling of a cattle stampede heading straight for his camp. After helping the traildrivers, they ask him to join the team. Mac takes them up on the offer—especially after he meets the cowgirl Colleen—and quickly impresses everyone with his cooking skills. There's just one more problem: Mac's new employers are rustlers, and the law is on their tail.
