K.C. arrives at a Marine firebase in Vietnam, a presumed "cherry," or new guy. He turns out to be a veteran fighter returning to the field after serious wounds. K.C. alienates everyone in his platoon as he refuses either friendship or help. On patrol, K.C. further angers his fellow Marines by his reluctance to look out for anyone but himself. While crossing rice paddies, K.C. apparently steps on a pressure-triggered mine which doesn't explode, but may if he steps off of it. In the broiling sun, K.C. must stand on the mine without relief until a demolition team can arrive to free him. Stranded for hours with only those he has alienated to protect him, K.C. learns new lessons about war and survival.
