In 1902 Texas, 13-year-old Horace goes to work on old Soll’s farm to earn enough money to buy a headstone for his father’s grave. Unfortunately for Horace, Soll’s senility, ill health, and obsession with the convict labor he uses to work the farm, make it unlikely that Horace will ever be paid the $12.50 Soll owes him for 6 months work.
