A young, strong slave girl and her mother are sold apart when their master (Massa Hensen) falls ill. As Julilly is sold from the plantation, she keeps thinking about a place called Canada that her mother told her about. She had said that if Jullilly got there she would be free, as slavery was not allowed there. The slaves left the Hensen plantation in Virginia to be taken to the Riley plantation Mississippi in the Deep South where Julilly met Liza, another slave girl. They escape together with two friends, Lester and Adam. Pursued by their master, they make their way through the United States to Canada on the Underground Railroad with the help of Alexander Milton Ross, a Canadian abolitionist. They eventually arrive safely, except for Adam, who dies of blood poisoning caused by his slave chains which were attached to the cart of slaves.
