Kodiak must stop an old war buddy, Buzz Howard, from terrorizing the countryside after a dynamite blast shocks him into believing he is fighting the war again under heavy combat conditions. Construction crewmen Buzz and Sam are about to detonate a dynamite charge when Buzz sees two hunters entering the danger zone. While trying on his two-way radio to get Sam not to detonate, Buzz dashes into the area. Sam doesn’t hear his radio and blasts. Buzz' mind is affected as the result of the concussion and he is triggered back to the Korean War. He runs amok, wounds a man, and then begins shooting up the countryside as if the people are the enemy.
