War correspondent Ernie Pyle joins Company C, 18th Infantry as this American army unit fights its way across North Africa in World War II. He comes to know the soldiers and finds much human interest material for his readers back in the States. Later, he catches up with the unit in Italy and accompanies it through the battles of San Vittorio and Cassino. He learns from its commanding officer, Lt. (later Capt.) Bill Walker of the loneliness of command, and from the individual G.I.'s of the human capacity to survive drudgery, discomfort, and the terror of combat.
