Narrated by Jake Baker, a 73-year-old who'd been sent to a nursing home by his niece, this novel recounts the adventures of Jake and Lucas Kraft after they leave a nursing home to become cowboys. Lucas is a writer whose pessimistic view of life is the opposite of Jake's. Never able to tell the truth about himself, Lucas has lost both fame and love but not his lust for life.
The two men hitchhike west (with a series of crazy drivers) and eventually find jobs on a Texas ranch. Jake falls in love with Betty, perhaps the foulest-mouthed cook ever invented; Lucas finds Sally Crandall, his ex-wife, a movie star, and the love of his life, who's performing in a cowboy-and-Indians movie not far from the ranch. Jake and Lucas actually do become cowboys (in the movie).
