The children of children keep coming

The dramatic odyssey opens with two anonymous slaves running to catch the Freedom Train, where at journey's end they hope to find liberation. Along the way, they encounter fields of laborers sowing seeds, plodding hard under sun high and moon low, working to end slavery. The toilers are sustained by work songs that at one moment express the dreams and fears of the downtrodden and at another moment burst forth with unbound faith and optimism.
