Tank

When Command Sergeant Major Zack Carey decides to retire from the military in peace, his plans are foiled by corrupt Sheriff Cyrus Buelton, who blackmails him into dropping charges against his son after planting evidence. With his tank and his family's help, Zack takes matters into his own hands, leading a daring series of chases and evasions through rural Georgia to free his son from prison. As the folk hero of the hour, Zack's vintage Sherman tank becomes an unlikely symbol of resistance against corruption, earning him a hero's welcome as he crosses into Tennessee in search of a fair extradition hearing.
