Convict Van Duff engineers a large-scale prison break; the six survivors hide out in a forgotten mine working near the prison, then set out on a long, dangerous journey by foot, car, train and truck to retrieve Duff's bank loot. En route, as they touch the lives of "regular folks," each has his own rendezvous with destiny.
