This documentary short profiles the role of Underground Railroad operative Mary Meachum in an attempt to free several enslaved people from St. Louis in the spring of 1855.  Meachum was arrested but prosecutors dropped the charges against her.  Today, people in the city annually commemorate her efforts (and the sacrifices of the captured enslaved families) at the Freedom Crossing site by the Mississippi River.
