An American army veteran grieves by the tombstones of his army company that died during World War I. Back home, he raises his sons in a pious setting and asks them to shun weapons. After a naughty fight turns awry, Desmond reads the Bible and vows not to harm another human in his life thereafter. Desmond then saves the life of a worker, experiencing a wholesome satisfaction in the process. In the hospital, he is smitten by a nurse, who he then dates. After the United States enters the Second World War, both sons enlist, adding to the ire of the father who despises his sons joining the Army.
