In 1971, a man calling himself D.B. Cooper hijacked a flight, claimed his ransom without harming a soul, and vanished. Elwood Reid uses this true story as a starting point, imagining Cooper as Phil Fitch, a Vietnam vet with a failed marriage who decides the time has come to do something that will save him from a life of punching timecards and wondering what could have been. Fitch ends up in Mexico, where he drifts until a bad turn of luck forces him to return home.

Meanwhile, newly retired FBI agent Frank Marshall is struggling with his new life of leisure-fishing, spending time with family, and drinking too much. Unable to let go of a few old cases, Marshall decides to help a young agent determined to solve the mystery of D. B. Cooper. As they close in and events bring Fitch back home, these two stories head for a moving climax in a smart, gripping, and frequently hilarious tale of one of America's modern folk heroes.
