In June of 1942 Germans and their collaborators decide to get rid of partisans and their stronghold in the woods of Mount Kozara in Northern Bosnia. They encircle the mountain and begin the mop up operation. Out gunned and outnumbered the partisans must not only take care of themselves but try to protect thousands of refugees too.
At a church in the country, eternally optimistic John marries Maria, his Atomic War Bride, as a war starts, planes buzz overhead and bombs start dropping. Though John is "mobilized" by the military seconds after the ceremony, he and Maria seek to be reunited.
After the war, a partisan hospital is set up in a monastery, with the nuns working as nurses. A beautiful young nun, Maria, becomes very fond of the partisan leader, Commissar Nenad.
