The night after Tom's burial, Legree rides to town, gets drunk, comes home, locks his door, and goes to bed. He wakes to see a ghost standing in the room, beckoning to him, and he faints. On the same night, shortly after Legree sees the ghost, the servants notice that the house door is open, and they see two white figures — actually Cassy and Emmeline — gliding down the lane. Cassy and Emmeline get to the next town, having changed out of their sheets and dressed as a Spanish Creole lady and her servant. Cassy, who has stolen some of Legree's money, buys a trunk and awaits the next riverboat. George Shelby is also waiting, and he and Cassy become acquainted. Cassy takes the young Kentuckian into her confidence when they board the boat, and George tells her he will do what he can to help her and Emmeline.
A French lady, Madame de Thoux, on the boat with her 12-year-old daughter, asks George about his home; she is interested in a slave who lived near there, George Harris. When George Shelby tells her the young man is married to his mother's servant Eliza and that both have escaped to Canada, Madame de Thoux tells him she is George Harris's sister, Emily. When Harris sold her to New Orleans, she was bought by a man who fell in love with her, took her to the West Indies, freed her, and married her; now she is a widow with a large inheritance and has come back to look for her brother. When George Shelby describes George Harris's wife, Eliza, Cassy realizes that Eliza is her own lost daughter.
Later, Cassy and Emmeline, together with Emily de Thoux, trace George and Eliza Harris to Montreal, where they have been living for five years and have had another child. The happy reunion soon changes Cassy into a devout Christian and a loving grandmother. George's sister wishes to share her inheritance with him and his family, and he accepts, saying he will use part of the money to educate himself. The whole family travels to France, where George attends a university for four years. Then, because of political upheavals in France, they return to the United States.
