What plan do huck and jim have?

Jim talks on and on about going to the free states, especially about his plan to earn money to buy the freedom of his wife and children. If their masters refuse to give up Jim’s family, Jim plans to have some abolitionists kidnap them.

Floating along, Huck and Jim pass several towns and worry that they have passed Cairo in the fog. They stop for the night and resolve to take the canoe upriver but in the morning discover that it has been stolen.
