In 1902, 13-year-old Horace toils on a run-down plantation in rural Texas to buy a tombstone for the father he lost a year earlier. Soll, the crusty old Confederate who owns the plantation and depends on convict labor to keep his farm running, takes a liking to Horace. However, Soll is aging and sinking into senility, making the possibility of Horace ever getting his pay increasingly unlikely. On Christmas Eve, as Soll becomes obsessed with his own mortality, he makes a grand promise... forcing Horace to confront his fear of death and the harsh truths of a decadent society.

In 1910, 19-year-old Horace Robedaux, still bitter toward his stepfather, goes to Houston to be reunited with his mother, Corella, and his sister, Lily Dale, following a long estrangement. He has not seen either since he was 12 because his wicked stepfather, Pete Davenport (whom his mother married after his father drank himself to death) believes a boy ought to be self-reliant.

In 1915, Elizabeth has fallen in love with Horace Robedaux, a young man her father condemns as a "wild boy." No matter how strict and protective, her parents cannot deter their daughter's growing independence.

In 1917, Elizabeth defies her wealthy parents by running off and marrying Horace Robedaux, a young man of humble prospects. Her parents have not spoken to her since - even though the couple lives in a rooming house nearby, they are struggling financially, and she is pregnant.

It's 1918, the height of United States involvement in World War I - Liberty Bonds are sold, German immigrants are suspected as traitors or saboteurs, young men everywhere succumb to the patriotism and propaganda and enlist. In a small Texas town, Horace Robedaux feels the pressure - he doesn't want to leave his young wife Elizabeth and their young child Jenny - but Elizabeth's can't-do-anything-right little brother is constantly talking about the war, and Elizabeth's stern father, who opposed the marriage initially, now has plans to take care of his daughter and the child so Horace can fight for his country. However, the influenza epidemic sweeping the town (and the nation) may change everyone's plans.

Two couples go to a mutual friend's wedding and end up swapping partners.
