Henry Carson, a schoolteacher from before the Civil War, arrives in a rugged Missouri hillside region and spends the night with the MacBean family: [Gill MacBean], his wife [Sairy MacBean], and their children, [Lissy Anne MacBean] and [Andrew MacBean]. Their other son, [Ben MacBean], has gone off to fight in the war, and the family’s hope of his safe return gradually fades as the fighting drags on.
[Gill MacBean] is wary of the stranger, unsure where his loyalties lie, but the rest of the family grows fond of the good-natured newcomer, especially [Lissy Anne]. Henry offers to help with the farm—the MacBeans are desperate for extra hands—yet Gill remains cautious about his motives. A band has been burning the barns of families loyal to the defeated Confederacy, and the MacBeans have just become their latest target, though Henry proves to be a hardworking helper.
When storekeeper and unofficial banker [Cal Baggett] visits to discuss repayment of a loan, Henry persuades him to host a “play party” that invites everyone—regardless of allegiance—to help heal the rift in the community. Gill strongly opposes the idea, but Henry deftly talks him into bringing his own family.
At first the two sides stay apart, but [Sairy MacBean] persuades [Dan Yeary] into dancing with her, breaking the ice. Soon the party is lively and warm, until an argument flares over a tune associated with the North. To avert a fight, Cal calls for a vote. The result is a tie, forcing [Henry Carson] to cast the deciding vote. When he reveals that he fought for the Union, the mood shifts, and the celebration dissolves into tension. The outcome pleases the Dessark camp, in particular [John Dessark] and his son [Badge Dessark], who watch with quiet satisfaction as the gathering collapses.
Henry is no longer welcome at the MacBeans, though he does not leave the area; instead, he starts building a schoolhouse, a quiet sign of his commitment to the community.
Eventually, Lissy Anne cannot bear to be apart from Henry and slips away with him in the night, with her mother’s blessing. Gill tracks them down with a bloodhound, intent on shooting his would-be son-in-law. As five masked nightriders close in, Henry knocks Gill unconscious and seizes his rifle. The horsemen open fire; Henry, taking cover, kills four and captures the fifth after a long chase and brutal fistfight at a burned-out dwelling. The captive is [Badge Dessark], who confesses that his father is behind the raids not out of loyalty to the South but for financial profit. The Dessarks are hanged, and the community begins to heal.
In a final, heartfelt revelation, Henry explains why he sought out the MacBeans. A flashback shows how he first met [Ben MacBean] as they walked across the hills to enlist in the war. They bonded in song and laughter, and, in a spur-of-the-moment race to the turn-off signpost, Henry ended up on the north branch while Ben went south. Their divergent loyalties stunned them, but Henry persuaded Ben to come with him. Two days before the war’s end, Ben was killed; before dying, he asked Henry to promise to help the MacBean harvest. Hearing this, Gill gives his blessing for Henry and Lissy Anne to wed, and the community looks toward a fragile but hopeful reconciliation.
