Jim Bludso is engineer of the Mississippi River packet the "Prairie Belle." He has a home in Gilgal, Ill., and a wife and twelve-month-old baby at the time the story opens, in 1861. A call is received for volunteers and he joins the Northern army. His wife is a Southern girl, and she opposes his joining the Union forces. The quarrel results in a separation and Jim goes to war. Ben Merrill, an unscrupulous contractor, meets Jim's wife in Natchez, her home town, and induces her to go with him to New Orleans. She deserts her baby and goes. In New Orleans a levee contractor comes to Merrill with the proposition that they take the contract for a new levee to be built at Gilgal. Merrill accepts and leaves New Orleans without telling the woman where he is going, and she is left to take care of herself. After the war Jim returns to Natchez and finds that his wife has deserted their little boy, and no one knows where she is.
