The postal worker Dragan witnesses historic events - the coup on September 9, 1944. Dragan completes his work duties with joy, stamps the letter and delivers them. He takes part in the nationalization of a factory. He educates himself in a political seminar. He helps the new director of the national militia. However, he finds it easier to deliver letters than to carry the gun given to him "just in case". Dragan gives back the weapon.
