Mattie, Johnny, and the Smooth White Stones
According to the Holy Hills Productions web site:
From the time that slavery began in the late 1600s until its end in 1863, thousands of slaves escaped to their freedom. Many were led by Harriet Tubman on the Underground Railroad. And then there were those who ran away into the night on their own. And then, there was... Mattie.
Mattie and Johnny are two slaves who are in love and hope to marry officially. They decide to runaway when Johnny learns that he will be sold in two days because the plantation owner found out that he had been teaching other slaves how to read and write. So, Mattie and Johnny plan to escape on the Underground Railroad.
They planned for Mattie to run off into the woods first and Johnny would meet her later by the tree with the Smooth White Stones arranged in the shape of a cross.
Something goes terribly wrong with their plan and audiences will be shocked to see what the combination of faith and love produced...
