On a hot day in Texas in the the 1890s, a stranger shows up at the small dairy farm of Royal and Ellie Thompson. He asks for work and is hired. He's a taciturn, English-speaking Swede from North Dakota; he's competent, strong, and good at farming and dairying. The years pass, the farm flourishes. Then one day a second stranger, also from North Dakota, Homer Hatch, arrives and lives are changed in ways no-one could have imagined.
