In this adventure, he goes to a Maryland plantation during the days of American slavery, where he meets a young girl named Sarah. When she learns that the owner has plans to sell her little brother, Jesse, to a plantation in the Deep South, it means they could be separated forever. Sarah takes their future into her own hands and decides there's only one way to run -- north.
