Uncle Tom
As described in a film magazine, Uncle Tom is an old slave living on George Shelby's plantation in Kentucky.  Along with Uncle Tom, are Eliza and her son Jim Crow. Shelby is in great debt, and although he doesn't want to, he must sell Uncle Tom and Jim to a slave trader.  Eliza hears that this is happening and decides to run away. She manages to escape by crossing an icy river despite being chased by bloodhounds.
