The atrocities of slavery are front and center in the new film 12 Years A Slave. It’s based on the story of Solomon Northup, a resident of Saratoga Springs in the early-to-mid-1800s. WXXI's Hélène Biandudi Hofer sits down with Northup's great great-granddaughter to learn more about his story, his legacy and the power of the human will.
