Carey decides to take matters into his own hands, delivers his resignation, and climbs into his vintage tank, destroying the local jail and police station and releasing Billy's lawyer. With Sarah tagging along, Carey departs for the county work farm, where they use the tank to liberate Billy and flee the town. His plan is to escape to neighboring Tennessee, where they can get a fair hearing regarding extradition. While repairing a shed track, though, Carey is injured, and Billy takes command of the Sherman.
