Jack Ritchie, a down-and-out writer moonlighting as a community college instructor, thinks he’s finally found his big break when 93-year-old Lucy Boomer — a former secretary, and perhaps more, to four U.S. Presidents — agrees to an interview for his book. In exchange for her revealing journals, Jack helps Lucy escape her Santa Fe nursing home and drive her home to North Dakota. Along the way, they pick up Anna, a free-spirited hitchhiker who disrupts their uneasy companionship. But their unlikely road trip takes an unexpected turn when a local detective sets out to track them down.
