Seventeen-year-old Isaiah Johnson leaves the farm to seek work in the East Texas oilfields. He's burdened with grief, feeling lonely and frightened.

Sixty-three-year-old Sam Smith is worn out and disillusioned by his work as a muleskinner.

When they cross paths, their beliefs about faith clash, but they bond over their shared experience as Black workers in a 1930s world dominated by white men. An unforeseen event teaches Isaiah and Sam how God can unite His children, no matter their skin color.
