A war has destroyed the United States of America, leaving the country in anarchy, its people defeated and all communications in ruins.
An army of warriors called the Holnists are determined to keep the struggling townships isolated from each other so they may continue their reign of terror and keep survivors devoid of the hope that life as they remembered it will ever return.
A stranger discovers the remains of a mail carrier's rusted jeep. Inside, he finds its driver's uniform and a sack full of undelivered mail.
He decides to wear this uniform, hoping it will make it easier for him to get food and shelter from the townspeople.
Instead, he discovers that the mail he carries serves as a reminder to the people of the way they once lived their lives.
Slowly, a new patriotism begins to take hold in the hearts of the countrymen. The mail he carries has become a symbol of hope, order and a reconnection with the places and loved ones of their past. Most importantly, it gives the citizenry the courage to battle the Holnists to regain control of their beloved country.
And the stranger, now named The Postman, becomes the reluctant leader of a revolt against the forces of destruction, the Holnists.
